Description

TITLE

OXAZOLINE AND THIAZOLINE ARTHROPODICIDES

BACKGROUND OF THE INVENTION

This invention relates to certain oxazoline and thiazoline compounds, their N-oxides, agriculturally-suitable salts and compositions, and methods of their use as arthropodicides in both agronomic and nonagronomic environments.

The control of arthropod pests is extremely important in achieving high crop efficiency. Arthropod damage to growing and stored agronomic crops can cause significant reduction in productivity and thereby result in increased costs to the consumer. The control of arthropod pests in forestry, greenhouse crops, ornamentals, nursery crops, stored food and fiber products, livestock, household, and public and animal health is also important. Many products are commercially available for these purposes, but the need continues for new compounds which are more effective, less costly, less toxic, environmentally safer or have different modes of action.

For example, C₁-C₃ alkylsulfonyl designates methylsulfonyl through propylsulfonyl; C₂ alkoxyalkyl designates CH₃OCH₂: C₃ alkoxyalkyl designates, for example, CH₃CH(OCH₃), CH₃OCH₂CH₂ or

CH₃CH₂OCH₂; and C₄ alkoxyalkyl designates the various isomers of an alkyl group substituted with an alkoxy group containing a total of four carbon atoms, examples including CH₃CH₂CH₂OCH₂ and CH₃CH₂OCH₂CH₂. Examples of "alkylcarbonyl" include C(O)CH₃, C(O)CH₂CH₂CH₃ and C(O)CH(CH₃)₂. Examples of

"alkoxycarbonyl" include CH₃OC(=O), CH₃CH₂OC(=O), CH₃CH₂CH₂OC(=O),

(CH₃)₂CHOC(=O) and the different butoxycarbonyl isomers. In the above recitations, when a compound of Formula I is comprised of one or more heterocyclic rings, all substituents are attached to these rings through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen.

The term "2,8,9-trioxa-5-aza-1-silabicyclo[3.3.3]undecan-1-yl" designates the silyl radical:

When a compound is substituted with a substituent bearing a subscript that indicates the number of said substituents can exceed 1 , said substituents (when they exceed 1) are independently selected from the group of defined substituents.

When a group contains a substituent which can be hydrogen, for example R² or

R¹⁰, then, when this substituent is taken as hydrogen, it is recognized that this is equivalent to said group being unsubstituted.

Compounds of this invention can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers. Accordingly, the present invention comprises compounds selected from Formula I, N-oxides and agriculturally suitable salts thereof. The compounds of the invention may be present as a mixture of stereoisomers, individual stereoisomers, or as an optically active form.

DETAILS OF THE INVENTION

The compounds of Formula I can be prepared by one or more of the following methods and variations as described in Schemes 1-14. The definitions of E, X, Y, Z, A, Q, J, R¹-R²⁴, M, J¹, W, W¹, m, n, p, q and t in the compounds of Formulae I-XIX below are as defined above in the Summary of the Invention.

Compounds of Formula I (R⁵ = H, X = -C(R^4a)₂A-) can be prepared by the reaction of a Formula II compound with a Formula HI compound in the presence of a base such as sodium hydride or lithium diisopropylamide (Scheme 1). The reaction may be run in the presence or absence of a solvent such as tetrahydrofuran (THF), dimethylformamide (DMF), ether, benzene or toluene. The reaction temperature can vary from 0°C to the boiling point of the solvent being used and is usually completed in less than 24 h.

Compounds of Formula II (Y = S) may be prepared by thionation of a Formula II compound (Y = O) with 2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4- disulfide (Lawesson's Reagent). Thionation reactions have been thoroughly reviewed by

M. Cava and M. Levinson in Tetrahedron (1987), 41, 5061-5087. This transformation is shown in Scheme 2.

Formula II compounds (Y = O) can be prepared by a condensation reaction between a propiolic acid of Formula IV (V = OH) and an amine of Formula V in the presence of a coupling agent such as dicyclohexylcarbodiimide (DCC). Typically, the reaction involves mixing a Formula IV compound (V = OH) with an equimolar amount of a Formula V compound in a suitable solvent such as methylene chloride, ethyl acetate or DMF and adding a slight excess of DCC. The reaction temperature can vary from 0-150°C. (A review of DCC coupling reactions can be found in Tetrahedron (1981), 37, 233). Alternatively, the condensation reaction can be performed with an acid chloride of Formula IV (V = Cl) and a Formula V compound in the presence of an acid scavenger (usually a tertiary amine base such as triethylamine) at room temperature or below. The reaction can be carried out in an inert solvent as methylene chloride, chloroform, benzene, tetrahydrofuran, toluene or other solvents that will not react with acid chlorides or bases. The reaction is normally completed in less than 24 h. (See Scheme 3). Other useful methods for the formation of amides are discussed in Larock, Comprehensive Organic Transformations, VCH Publishers, Inc., New York.

Scheme 4 illustrates the preparation of Formula IV compounds. An acrylate of Formula VI is brominated with bromine in an inert solvent such as methylene chloride, carbon tetrachloride, chloroform or ether followed by dehydrobromination of the dibromo intermediate with a base such as sodium hydroxide or potassium hydroxide. The reaction may be run in a solvent such as methanol, ethanol, water or DMF. An example of this transformation can be found in Organic Synthesis, Coll. Vol. II, p 270. Alternative methods of making compounds of Formula IV (V = OH) have been described by Chenault and Dupin in Synthesis (1987), 498, by Yamanaka et al. in Synthesis (1992), 746 and by Hendrickson and Hussoin in Synthesis (1989), 217. A Formula IV compound (V = OH) can further be transformed into a Formula IV compound (V = Cl) using conventional methods of converting a carboxylic acid into an acid chloride. (See Larock, Comprehensive Organic Transformations, VCH Publishers, Inc., New York).

Compounds of Formula VI (L = Me, Et) can be prepared by the reaction of aldehydes of Formula VII with phosphonium salts of Formula VIII (L = Me, Et) in the presence of a strong base. Aldehydes of Formula VII and phosphonium salts of Formula VIII are commercially available or can be prepared by known methods. A typical reaction involves mixing a Formula VIII compound with a strong base such as an alkyllithium (e.g., butyllithium), a metal alkoxide (e.g., sodium methoxide), sodium amide or sodium hydride in a suitable solvent such as tetrahydrofuran, ether, benzene, methanol, toluene, acetonitrile, dimethoxyethane and dimethyl sulfoxide, followed by addition of an aldehyde of Formula VII. The temperature of the reaction can vary from

-70-200°C with a preferred temperature range of 0-100°C. The Wittig reaction has been reviewed by Maercker in Organic Reactions (1965), 14, 270-490. The transformation is illustrated in Scheme 5.

, .

Alternatively, compounds of Formula I can be prepared by an aldol-type condensation of a Formula IX compound with an aldehyde of Formula VII. Scheme 6 illustrates this transformation. The reaction can be run in the presence of a base such as a metal alkoxide, e.g., sodium methoxide, or an amine base as piperidine or

1,4-diazabicyclo[2.2.2]octane (DABCO). A suitable solvent for this transformation can be chosen from, but not limited to, methanol, ethanol, water, xylene, DMF, dioxane or THF. The reaction temperature can vary from 0-200°C and the reaction is done in less than 48 h. An example of this reaction can be found in Organic Synthesis, Coll. Vol. 5, (1973), p 627.

Scheme 7 shows the preparation of compounds of Formula IX (where

X = -A(CH₂)_n-). The reaction involves the cyclization of a Formula X compound with a compound of Formula XI in the presence of a base. Compounds of Formula XI are commercially available or can be prepared by known methods. Examples of bases that can be used include sodium hydride or potassium t-Bu toxide. The reaction may be run in a solvent such as benzene, THF, ether, toluene, DMF, dimethyl sulfoxide (DMSO) or dioxane. The reaction temperature may vary from 0-200°C and the reaction is usually done within 24 h.

Compounds of Formula X (Y = O) can be prepared by reaction of a carboxylic acid of Formula XII with an amine of Formula V. Compounds of Formula XII are commercially available or can be prepared by known methods. The reaction conditions are as described for Scheme 3.

Compounds of Formula IX (where X is -CH₂(CH₂)_n-) can be prepared by cyclization of a bromide of Formula XIII in the presence of a base as shown in Scheme 9. Reaction conditions are similar to those of Scheme 7.

Scheme 10 illustrates the synthesis of compounds of Formula XIII. The reaction involves the coupling of an acid of Formula XIV with an amine of Formula V as described for Scheme 3.

Compounds of Formula V can be prepared by the reaction of compounds of Formula XV with sodium hypobromite (or sodium hydroxide and bromine). This transformation is shown in Scheme 11. A review of the Hofmann rearrangement can be found in Organic Reactions (1946), 3, 267-306. A typical reaction involves the addition of a compound of Formula XIII to an aqueous solution of sodium hypobromite. The temperature of the reaction can range from 0-200°C with the preferred temperature range between 30-100°C. The reaction is usually complete in 24 h. Alternatively, the transformation can be accomplished by treating a Formula XV compound with

[hydroxy(tosyloxy)iodo]benzene in refluxing acetonitrile. (See J. Org. Chem. (1986), 51, 2669-2671).

Compounds of Formula XV can be prepared by reacting compounds of

Formula XVI with ammonia. This transformation is shown in Scheme 12. The reaction can be run in solvents such as methanol, ethanol, ether, benzene and toluene. Typical reactions are carried out at ambient temperature, and reactions are usually completed in 24 h. For reference, see D. W. Jones, J. Chem. Soc. (1969), 1729.

Compounds of Formula XVI can be prepared by the reaction of serine derivatives (Formula XVII) with an imidate of Formula XVIII as shown in Scheme 13. Serine derivatives of Formula XVIII are commercially available or can be prepared by known methods. The reaction can be carried out in solvents such as methanol, methylene chloride, chloroform, benzene, dioxane and tetrahydrofuran. Water can be added as a cosolvent. The reaction can be carried out at temperatures varying from 0°C to the reflux temperature of the particular solvent being used, and the reaction is usually complete in 24 h. For reference, see Agric. Biol. Chem. (1986), 50, 615-623.

As depicted in Scheme 14, imidates of Formula XVI can be prepared from amides of Formula XVII by reaction with a trialkyloxonium tetrafluoroborate in an inert solvent such as methylene chloride, benzene or toluene. Amides of Formula XVII are commercially available or can be prepared by known methods. The syntheses of imidates has been extensively reviewed by D. A. Neilson in The Chemistry of Amidines and Imidates, Patai and Rappoport, Eds., Vol. 2, (1991), pp 425-483.

It is recognized that some reagents and reaction conditions described above for preparing compounds of Formula I may not be compatible with certain functionalities present in the intermediates. In these instances, the incorporation of

protection/deprotection sequences or functional group interconversions into the synthesis will aid in obtaining the desired products. The use and choice of the protecting groups will be apparent to one skilled in chemical synthesis (see, for example, Greene, T. W.; Wuts, P. G. M. Protective Groups in Organic Synthesis, 2nd ed.; Wiley: New York, 1991). One skilled in the art will recognize that, in some cases, after the introduction of a given reagent as it is depicted in any individual scheme, it may be necessary to perform additional routine synthetic steps not described in detail to complete the synthesis of compounds of Formula I. One skilled in the art will also recognize that it may be necessary to perform a combination of the steps illustrated in Schemes 1-? in an order other than that implied by the particular sequence presented to prepare the compounds of Formula I. One skilled in the art will also recognize that compounds of Formula I and the intermediates described herein can be subjected to various electrophilic, nucleophilic, radical, organometallic, oxidation, and reduction reactions to add substituents or modify existing substituents.

Without further elaboration, it is believed that one skilled in the art using the preceding description can utilize the present invention to its fullest extent. The following Examples are, therefore, to be construed as merely illustrative, and not limiting of the disclosure in any way whatsoever. Percentages are by weight except for

chromatographic solvent mixtures or where otherwise indicated. Parts and percentages for chromatographic solvent mixtures are by volume unless otherwise indicated.

Formulation / Utility

Compounds of this invention will generally be used as a formulation or composition with an agriculturally suitable carrier comprising at least one of a liquid diluent, a solid diluent or a surfactant. The formulation or composition ingredients are selected to be consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature. Useful formulations include liquids such as solutions (including emulsifiable

concentrates), suspensions, emulsions (including microemulsions and/or suspoemulsions) and the like which optionally can be thickened into gels. Useful formulations further include solids such as dusts, powders, granules, pellets, tablets, films, and the like which can be water-dispersible ("wettable") or water-soluble. Active ingredient can be

(micro)encapsulated and further formed into a suspension or solid formulation;

alternatively the entire formulation of active ingredient can be encapsulated (or

"overcoated"). Encapsulation can control or delay release of the active ingredient.

Sprayable formulations can be extended in suitable media and used at spray volumes from about one to several hundred liters per hectare. High-strength compositions are primarily used as intermediates for further formulation.

The formulations will typically contain effective amounts of active ingredient, diluent and surfactant within the following approximate ranges which add up to 100 percent by weight.

Typical solid diluents are described in Watkins, et al., Handbook of Insecticide Dust Diluents and Carriers, 2nd Ed., Dorland Books, Caldwell, New Jersey. Typical liquid diluents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, New York, 1950. McCutcheon's Detergents and Emulsifiers Annual, Allured Publ. Corp., Ridgewood, New Jersey, as well as Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth and the like, or thickeners to increase viscosity.

Surfactants include, for example, polyethoxylated alcohols, polyethoxylated alkylphenols, polyethoxylated sorbitan fatty acid esters, dialkyl sulfosuccinates, alkyl sulfates, alkylbenzene sulfonates, organosilicones, N,N-dialkyltaurates, lignin sulfonates, naphthalene sulfonate formaldehyde condensates, polycarboxylates, and polyoxyethylene/polyoxypropylene block copolymers. Solid diluents include, for example, clays such as bentonite, montmorillonite, attapulgite and kaolin, starch, sugar, silica, talc, diatomaceous earth, urea, calcium carbonate, sodium carbonate and bicarbonate, and sodium sulfate. Liquid diluents include, for example, water,

N,N-dimethylformamide, dimethyl sulfoxide, N-alkylpyrrolidone, ethylene glycol, polypropylene glycol, paraffins, alkylbenzenes, alkylnaphthalenes, oils of olive, castor, linseed, tung, sesame, corn, peanut, cotton-seed, soybean, rape-seed and coconut, fatty acid esters, ketones such as cyclohexanone, 2-heptanone, isophorone and 4-hydroxy-4- methyl-2-pentanone, and alcohols such as methanol, cyclohexanol, decanol and tetrahydrofurfuryl alcohol.

Solutions, including emulsifiable concentrates, can be prepared by simply mixing the ingredients. Dusts and powders can be prepared by blending and, usually, grinding as in a hammer mill or fluid-energy mill. Suspensions are usually prepared by wet-milling; see, for example, U.S. 3,060,084. Granules and pellets can be prepared by spraying the active material upon preformed granular carriers or by agglomeration techniques. See Browning, "Agglomeration", Chemical Engineering, December 4, 1967, pp 147-48, Perry's Chemical Engineer's Handbook, 4th Ed., McGraw-Hill, New York, 1963, pages 8-57 and following, and WO 91/13546. Pellets can be prepared as described in

U.S. 4,172,714. Water-dispersible and water-soluble granules can be prepared as taught in U.S. 4, 144,050, U.S. 3,920,442 and DE 3,246,493. Tablets can be prepared as taught in U.S. 5,180,587, U.S. 5,232,701 and U.S. 5,208,030. Films can be prepared as taught in GB 2.095,558 and U.S. 3,299,566.

Arthropod pests are controlled and protection of agronomic, horticultural and specialty crops, animal and human health is achieved by applying one or more of the compounds of this invention, in an effective amount, to the environment of the pests including the agronomic and/or nonagronomic locus of infestation, to the area to be protected, or directly on the pests to be controlled. Thus, the present invention further comprises a method for the control of foliar and soil inhabiting arthropods and nematode pests and protection of agronomic and/or nonagronomic crops, comprising applying one or more of the compounds of the invention, or compositions containing at least one such compound, in an effective amount, to the environment of the pests including the agronomic and/or nonagronomic locus of infestation, to the area to be protected, or directly on the pests to be controlled. A preferred method of application is by spraying. Alternatively, granular formulations of these compounds can be applied to the plant foliage or the soil. Other methods of application include direct and residual sprays, aerial sprays, seed coats, microencapsulations, systemic uptake, baits, eartags, boluses, foggers, fumigants, aerosols, dusts and many others. The compounds can be

incorporated into baits that are consumed by the arthropods or in devices such as traps and the like.

The compounds of this invention can be applied in their pure state, but most often application will be of a formulation comprising one or more compounds with suitable carriers, diluents, and surfactants and possibly in combination with a food depending on the contemplated end use. A preferred method of application involves spraying a water dispersion or refined oil solution of the compounds. Combinations with spray oils, spray oil concentrations, spreader stickers, adjuvants, other solvents, and synergists such as piperonyl butoxide often enhance compound efficacy. The rate of application required for effective control will depend on such factors as the species of arthropod to be controlled, the pest's life cycle, life stage, its size, location, time of year, host crop or animal, feeding behavior, mating behavior, ambient moisture, temperature, and the like. Under normal circumstances, application rates of about 0.01 to 2 kg of active ingredient per hectare are sufficient to control pests in agronomic ecosystems, but as little as 0.001 kg/hectare may be sufficient or as much as 8 kg hectare may be required. For nonagronomic applications, effective use rates will range from about 1.0 to 50 mg/square meter but as little as 0.1 mg/square meter may be sufficient or as much as 150 mg/square meter may be required.

The following TESTS demonstrate the control efficacy of compounds of this invention on specific pests. "Control efficacy" represents inhibition of arthropod development (including mortality) that causes significantly reduced feeding. The pest control protection afforded by the compounds is not limited, however, to these species. See Index Tables A-C for compound descriptions.

BIOLOGICAL EXAMPLES OF THE INVENTION TEST A

Fall Armyworm

Test units, each consisting of a H.I.S. (high impact styrene) tray with 16 cells were prepared. Wet filter paper and approximately 8 cm² of lima bean leaf was placed into twelve of the cells. A 0.5-cm layer of wheat germ diet was placed into the four remaining cells. Fifteen to twenty third-instar larvae of fall armyworm (Spodoptera frugiperda) were placed into a 230-mL (8-ounce) plastic cup. Solutions of each of the test compounds in 75:25 acetone-distilled water solvent were sprayed into the tray and cup. Spraying was accomplished by passing the tray and cup on a conveyer belt directly beneath a flat fan hydraulic nozzle which discharged the spray at a rate of 0.55 kilograms of active ingredient per hectare (about 0.5 pounds per acre) at 207 kPa (30 p.s.i.). The insects were transferred from the 230-mL cup to the H.I.S. tray (one insect per cell). The trays were covered and held at 27°C and 50% relative humidity for 48 hours, after which time readings were taken on the twelve cells with lima bean leaves. The four remaining cells were read at 6-8 days for delayed toxicity. Of the compounds tested, the following gave control efficacy levels of 80% or greater: 20.

TEST B

Two-Spotted Spider Mite

Pieces of kidney bean leaves, each approximately 6.5 cm² (1 square inch) in area, that had been infested on the undersides with 25 to 30 adult mites (Tetranychus urticae), were sprayed with their undersides facing up on a hydraulic sprayer with a solution of the test compound in 75:25 acetone-distilled water solvent. Spraying was accomplished by passing the leaves, on a conveyor belt, directly beneath a flat fan hydraulic nozzle which discharged the spray at a rate of 0.55 kilograms of active ingredient per hectare (about 0.5 pounds per acre) at 207 kPa (30 p.s.i.). The leaf squares were then placed underside-up on a square of wet cotton in a petri dish and the perimeter of the leaf square was tamped down onto the cotton with forceps so that the mites could not escape onto the untreated leaf surface. The test units were held at 27°C and 50% relative humidity for 48 hours, after which time mortality readings were taken. Of the compounds tested, the following gave mortality levels of 80% or higher:

The same units were held an additional 5 days and read for larvicide/ovicide mortality and/or developmental effects. Of the compounds tested, the following gave activity levels of 80% or higher: 20.

TEST C

Larval two-Spotted Spider Mites (Tetranychus urticae)

Solutions of the test compounds were prepared by dissolving in a minimum of acetone and then adding water containing a wetting agent until the concentration of the compound was 50 ppm. Two- week old red kidney bean plants infested with two-spotted spider mites eggs were sprayed to run-off (equivalent to 28 g/ha) with the test solution using a turntable sprayer. Plants were held in a chamber at 25°C and 50% relative humidity. Of the compounds tested, the following gave larvicide/ovicide activity of 80% or higher seven days after spraying: 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 15, 17, 18*, 19*, 20*, 21*, 22*, 23*, 29*. 31*, and 32*.

*Compound was tested at 5 ppm (equivalent to 2.8 g/ha).

TEST D

Fall Armyworm Whole Plant Test

Solutions of the test compounds were prepared by dissolving in a minimum of acetone and adding water containing a wetting agent until the concentration of the compounds was 10 ppm. Test compounds were then sprayed to run-off (equivalent to 5.5 g/ha) onto soybean plants utilizing a rotating platform and an atomizing sprayer. Treated plants were dried, and fall armyworm (Spodoptera frugiperda) larvae were exposed to excised, treated leaves. Test units were held at 27°C and 50% relative humidity, and evaluated for larval mortality 120 h post-infestation. Of the compounds tested, the following gave mortality levels of 80% or higher: 1, 3, 7*, 15, 18, 19, 21, 22, 23, 24, 26, 28, and 31.

*Compound was tested at 3 ppm (equivalent to 1.7 g/ha).
