[0021] Additionally, another embodiment of the present disclosure is a composition useful for protecting a plant against attack by a phytopathogenic organism and/or treatment of a plant infested by a phytopathogenic organism comprising a compound of Formula I and a phytologically acceptable carrier material. DETAILED DESCRIPTION
[0022] The compounds of the present disclosure may be applied by any of a variety of known techniques, either as the compounds or as formulations comprising the compounds. For example, the compounds may be applied to the roots or foliage of plants for the control of various fungi, without damaging the commercial value of the plants. The materials may be applied in the form of any of the generally used formulation types, for example, as solutions, dusts, wettable powders, flowable concentrate, or emulsifiable concentrates.
[0023] Preferably, the compounds of the present disclosure are applied in the form of a formulation, comprising one or more of the compounds of Formula I with a phytologically acceptable carrier. Concentrated formulations may be dispersed in water, or other liquids, for application, or formulations may be dust-like or granular, which may then be applied without further treatment. The formulations can be prepared according to procedures that are conventional in the agricultural chemical art.
[0024] The present disclosure contemplates all vehicles by which one or more of the compounds may be formulated for delivery and use as a fungicide. Typically, formulations are applied as aqueous suspensions or emulsions. Such suspensions or emulsions may be produced from water-soluble, water-suspendible, or emulsifiable formulations which are solids, usually known as wettable powders; or liquids, usually known as emulsifiable concentrates, aqueous suspensions, or suspension concentrates. As will be readily appreciated, any material to which these compounds may be added may be used, provided it yields the desired utility without significant interference with the activity of these compounds as antifungal agents.
[0025] Wettable powders, which may be compacted to form water-dispersible granules, comprise an intimate mixture of one or more of the compounds of Formula I, an inert carrier and surfactants. The concentration of the compound in the wettable powder may be from about 10 percent to about 90 percent by weight based on the total weight of the wettable powder, more preferably about 25 weight percent to about 75 weight percent. In the preparation of wettable powder formulations, the compounds may be compounded with any finely divided solid, such as prophyllite, talc, chalk, gypsum, Fuller's earth, bentonite, attapulgite, starch, casein, gluten, montmorillonite clays, diatomaceous earths, purified silicates or the like. In such operations, the finely divided carrier and surfactants are typically blended with the compound(s) and milled. [0026] Emulsifiable concentrates of the compounds of Formula I may comprise a convenient concentration, such as from about 1 weight percent to about 50 weight percent of the compound, in a suitable liquid, based on the total weight of the concentrate. The compounds may be dissolved in an inert carrier, which is either a water-miscible solvent or a mixture of water-immiscible organic solvents, and emulsifiers. The concentrates may be diluted with water and oil to form spray mixtures in the form of oil-in-water emulsions. Useful organic solvents include aromatics, especially the high-boiling naphthalenic and olefinic portions of petroleum such as heavy aromatic naphtha. Other organic solvents may also be used, for example, terpenic solvents, including rosin derivatives, aliphatic ketones, such as cyclohexanone, and complex alcohols, such as 2- ethoxyethanol.
[0027] Emulsifiers which may be advantageously employed herein may be readily determined by those skilled in the art and include various nonionic, anionic, cationic and amphoteric emulsifiers, or a blend of two or more emulsifiers. Examples of nonionic emulsifiers useful in preparing the emulsifiable concentrates include the polyalkylene glycol ethers and condensation products of alkyl and aryl phenols, aliphatic alcohols, aliphatic amines or fatty acids with ethylene oxide, propylene oxides such as the ethoxylated alkyl phenols and carboxylic esters solubilized with the polyol or polyoxyalkylene. Cationic emulsifiers include quaternary ammonium compounds and fatty amine salts. Anionic emulsifiers include the oil-soluble salts (e.g., calcium) of alkylaryl sulphonic acids, oil-soluble salts or sulfated polyglycol ethers and appropriate salts of phosphated polyglycol ether.
[0028] Representative organic liquids which may be employed in preparing the emulsifiable concentrates of the compounds of the present disclosure are the aromatic liquids such as xylene, propyl benzene fractions; or mixed naphthalene fractions, mineral oils, substituted aromatic organic liquids such as dioctyl phthalate; kerosene; dialkyl amides of various fatty acids, particularly the dimethyl amides of fatty glycols and glycol derivatives such as the n-butyl ether, ethyl ether or methyl ether of diethylene glycol, the methyl ether of Methylene glycol, petroleum fractions or hydrocarbons such as mineral oil, aromatic solvents, paraffinic oils, and the like; vegetable oils such as soy bean oil, rape seed oil, olive oil, castor oil, sunflower seed oil, coconut oil, corn oil, cotton seed oil, linseed oil, palm oil, peanut oil, safflower oil, sesame oil, tung oil and the like; esters of the above vegetable oils; and the like. Mixtures of two or more organic liquids may also be employed in the preparation of the emulsifiable concentrate. Organic liquids include xylene, and propyl benzene fractions, with xylene being most preferred in some cases. Surface-active dispersing agents are typically employed in liquid formulations and in an amount of from 0.1 to 20 percent by weight based on the combined weight of the dispersing agent with one or more of the compounds. The formulations can also contain other compatible additives, for example, plant growth regulators and other biologically active compounds used in agriculture.
[0029] Aqueous suspensions comprise suspensions of one or more water-insoluble compounds of Formula I, dispersed in an aqueous vehicle at a concentration in the range from about 1 to about 50 weight percent, based on the total weight of the aqueous suspension. Suspensions are prepared by finely grinding one or more of the compounds, and vigorously mixing the ground material into a vehicle comprised of water and surfactants chosen from the same types discussed above. Other components, such as inorganic salts and synthetic or natural gums, may also be added to increase the density and viscosity of the aqueous vehicle.
[0030] The compounds of Formula I can also be applied as granular formulations, which are particularly useful for applications to the soil. Granular formulations generally contain from about 0.5 to about 10 weight percent, based on the total weight of the granular formulation of the compound(s), dispersed in an inert carrier which consists entirely or in large part of coarsely divided inert material such as attapulgite, bentonite, diatomite, clay or a similar inexpensive substance. Such formulations are usually prepared by dissolving the compounds in a suitable solvent and applying it to a granular carrier which has been preformed to the appropriate particle size, in the range of from about 0.5 to about 3 mm. A suitable solvent is a solvent in which the compound is substantially or completely soluble. Such formulations may also be prepared by making a dough or paste of the carrier and the compound and solvent, and crushing and drying to obtain the desired granular particle.
[0031] Dusts containing the compounds of Formula I may be prepared by intimately mixing one or more of the compounds in powdered form with a suitable dusty agricultural carrier, such as, for example, kaolin clay, ground volcanic rock, and the like. Dusts can suitably contain from about 1 to about 10 weight percent of the compounds, based on the total weight of the dust.
[0032] The formulations may additionally contain adjuvant surfactants to enhance deposition, wetting and penetration of the compounds onto the target crop and organism. These adjuvant surfactants may optionally be employed as a component of the formulation or as a tank mix. The amount of adjuvant surfactant will typically vary from 0.01 to 1.0 percent by volume, based on a spray-volume of water, preferably 0.05 to 0.5 volume percent. Suitable adjuvant surfactants include, but are not limited to ethoxylated nonyl phenols, ethoxylated synthetic or natural alcohols, salts of the esters or sulphosuccinic acids, ethoxylated organosilicones, ethoxylated fatty amines, blends of surfactants with mineral or vegetable oils, crop oil concentrate (mineral oil (85%) + emulsifiers (15%)); nonylphenol ethoxylate; benzylcocoalkyldimethyl quaternary ammonium salt; blend of petroleum hydrocarbon, alkyl esters, organic acid, and anionic surfactant; C9- Cn
alkylpolyglycoside; phosphated alcohol ethoxylate; natural primary alcohol (C12- C16) ethoxylate; di-sec-butylphenol EO-PO block copolymer; polysiloxane-methyl cap; nonylphenol ethoxylate + urea ammonium nitrrate; emulsified methylated seed oil; tridecyl alcohol (synthetic) ethoxylate (8EO); tallow amine ethoxylate (15 EO); PEG(400) dioleate-99. The formulations may also include oil-in-water emulsions such as those disclosed in U.S. Patent Application Serial No. 11/495,228, the disclosure of which is expressly incorporated by reference herein.
[0033] The formulations may optionally include combinations that contain other pesticidal compounds. Such additional pesticidal compounds may be fungicides, insecticides, herbicides, nematocides, miticides, arthropodicides, bactericides or combinations thereof that are compatible with the compounds of the present disclosure in the medium selected for application, and not antagonistic to the activity of the present compounds. Accordingly, in such embodiments, the other pesticidal compound is employed as a supplemental toxicant for the same or for a different pesticidal use. The compounds of Formula I and the pesticidal compound in the combination can generally be present in a weight ratio of from 1:100 tol00:l.
[0034] The compounds of the present disclosure may also be combined with other fungicides to form fungicidal mixtures and synergistic mixtures thereof. The fungicidal compounds of the present disclosure are often applied in conjunction with one or more other fungicides to control a wider variety of undesirable diseases. When used in conjunction with other fungicide(s), the presently claimed compounds may be formulated with the other fungicide(s), tank-mixed with the other fungicide(s) or applied sequentially with the other fungicide(s).

[0037] Another embodiment of the present disclosure is a method for the control or prevention of fungal attack. This method comprises applying to the soil, plant, roots, foliage, or locus of the fungus, or to a locus in which the infestation is to be prevented (for example applying to cereal or grape plants), a fungicidally effective amount of one or more of the compounds of Formula I. The compounds are suitable for treatment of various plants at fungicidal levels, while exhibiting low phytotoxicity. The compounds may be useful both in a protectant and/or an eradicant fashion.
[0038] The compounds have been found to have significant fungicidal effect particularly for agricultural use. Many of the compounds are particularly effective for use with agricultural crops and horticultural plants.
[0039] It will be understood by those in the art that the efficacy of the compound for the foregoing fungi establishes the general utility of the compounds as fungicides.
[0040] The compounds have broad ranges of activity against fungal pathogens. Exemplary pathogens may include, but are not limited to, causing agent of wheat leaf blotch (Mycosphaerella graminicola; impect stage: Septoria tritici), wheat brown rust (Puccinia triticina), wheat stripe rust (Puccinia striiformis), scab of apple (Venturia inaequalis), powdery mildew of grapevine {Uncinula necator), barley scald (Rhynchosporium secalis), blast of rice {Magnaporthe grisea), rust of soybean (Phakopsora pachyrhizi), glume blotch of wheat (Leptosphaeria nodorum), powdery mildew of wheat (Blumeria graminisf. sp.tritici), powdery mildew of barley (Blumeria graminisf. sp. hordei), powdery mildew of cucurbits (Erysiphe cichoracearum), anthracnose of cucurbits (Glomerella lagenarium), leaf spot of beet {Cercospora beticola), early blight of tomato {Alternaria solani), and spot blotch of barley {Cochliobolus sativus). The exact amount of the active material to be applied is dependent not only on the specific active material being applied, but also on the particular action desired, the fungal species to be controlled, and the stage of growth thereof, as well as the part of the plant or other product to be contacted with the compound. Thus, all the compounds, and formulations containing the same, may not be equally effective at similar concentrations or against the same fungal species.
[0041] The compounds are effective in use with plants in a disease-inhibiting and phytologically acceptable amount. The term "disease-inhibiting and phytologically acceptable amount" refers to an amount of a compound that kills or inhibits the plant disease for which control is desired, but is not significantly toxic to the plant. This amount will generally be from about 0.1 to about 1000 ppm (parts per million), with 1 to 500 ppm being preferred. The exact concentration of compound required varies with the fungal disease to be controlled, the type of formulation employed, the method of application, the particular plant species, climate conditions, and the like. A suitable application rate is typically in the range from about 0.10 to about 4 pounds/acre (about 0.01 to 0.45 grams per square meter, g/m ).
[0042] Any range or desired value given herein may be extended or altered without losing the effects sought, as is apparent to the skilled person for an understanding of the teachings herein.
[0043] The compounds of Formula I may be made using well-known chemical procedures. Intermediates not specifically mentioned in this disclosure are either commercially available, may be made by routes disclosed in the chemical literature, or may be readily synthesized from commercial starting materials utilizing standard procedures.

Chlorotriisopropylsilane (21.74 mL, 102 mmol) was then added via syringe over 30 minutes. The reaction mixture was allowed to warm to room temperature as the ice melted and stirred overnight. After 18 h, TLC indicated consumption of starting material. The reaction mixture was poured into a separatory funnel and washed with H20 (100 mL), saturated aqueous NaHC03 (100 mL), brine (100 mL), 1M HC1 (100 mL), then brine (100 mL). The organic layer was passed through a phase separator and concentrated to afford a clear, colorless oil. The oil was purified by flash column chromatography (silica gel (Si02), 0~ 10% ethyl acetate in hexanes) to afford the title compound (21.68 g, 79 mmol, 93 % yield) as a clear, colorless oil: 1H NMR (400 MHz, CDC13) δ 4.41 (q, J = 6.7 Hz, 1H), 4.18 (qd, J = 7.1, 2.7 Hz, 2H), 1.43 (d, J = 6.7 Hz, 3H), 1.28 (t, J = 7.1 Hz, 3H), 1.17 0.97 (m, 21H); 13C NMR (101 MHz, CDC13) δ 174.23, 68.55, 60.66, 21.80, 17.85, 14.22, 12.16; Rf = 0.73 in 10% Ethyl acetate : hexanes, one UV-inactive spot (KMn04 stain).

The resultant clear, colorless solution was cooled to -78 °C in an acetone/dry ice bath. (S)-2-((triisopropylsilyl)oxy)propanal (4.61 g, 20.01 mmol) was added as a solution in anhydrous Et20 (60 mL) via syringe over 1.5 h. The clear, colorless reaction was cooled for an additional 1.5 h at -78 °C, after which TLC indicated consumption of starting material. MeOH (50 mL) was then added, and the reaction was stirred for 5 min at -78 °C. pH 7 buffer (70 mL) was added, and the reaction was warmed to 0 °C in an ice/water bath. H202 (30%, 60 mL) was then added, and the resulting biphasic reaction mixture was vigorously stirred at 0 °C for 2.5 h, and then warmed to room temperature as the ice melted and stirred for 30 h. The layers were separated, and the aqueous phase was extracted with El^O (3 x 100 mL). The aqueous layer was carefully quenched with saturated aqueous Na^Og on ice until KI- starch test paper indicated the disappearance of residual H202. The combined organic layers were dried over MgS04, filtered, and concentrated to a clear oil. The oil was purified by flash column chromatography (Si02, 0" 5% ethyl acetate in hexanes) to afford the title compound (5.00 g, 18.33 mmol, 92% yield) as a clear, light rose colored oil: 1H NMR (400 MHz, CDC13) δ 5.85 (ddt, = 17.2, 10.2, 7.0 Hz, 1H), 5.22 - 4.97 (m, 2H), 3.93 (qd, J = 6.2, 3.3 Hz, 1H), 3.70 (ddt, J = 8.3, 5.7, 2.9 Hz, 1H), 2.34 (d, 7 = 2.6 Hz, 1H), 2.30 - 2.09 (m, 2H), 1.14 (d, J = 6.3 Hz, 3H), 1.12 - 1.03 (m, 21H); 13C NMR (101 MHz, CDC13) δ 134.91, 117.07, 74.48, 70.77, 36.72, 18.06, 16.59, 12.37; IR (neat) 3480, 2943, 2866, 1463, 1067, 881 cm_1; HRMS-ESI (mJz) calcd for [Ci5H3302Si]+,

Figure imgf000029_0001
[0065] In a 250 mL round-bottom flask, a suspension of sodium hydride (0.441 g, 11.04 mmol) was prepared in DMF (45.7 mL) under an atmosphere of N2 and cooled to 0 °C in an ice/water bath. After 5 min, (2S,3 ?)-2-((triisopropylsilyl)oxy)hex-5-en-3-ol (2.005 g, 7.36 mmol) was added via syringe as a solution in DMF (6 mL with 2 x 3 mL washes) over 5 min. The resulting bright yellow reaction mixture was brought to room temperature and stirred for 2 h, during which time bubbling was observed and the reaction progressed from bright yellow to orange. The reaction was cooled to 0 °C and tetrabutylammonium iodide (0.272 g, 0.736 mmol) was added in one portion followed by 4-methoxybenzyl bromide (1.716 mL, 11.77 mmol), after which the reaction underwent a distinct color change to light yellow. The reaction mixture was warmed to room temperature and stirred for 2 h. TLC indicated incomplete consumption of starting material and additional tetrabutylammonium iodide (0.272 g, 0.736 mmol) and 4-methoxybenzyl bromide (1.716 mL, 11.77 mmol) was added.

[00112] Technical grades of materials were dissolved in acetone, which were then mixed with nine volumes of water containing 110 ppm Triton X-100. The fungicide solutions were applied onto wheat seedlings using an automated booth sprayer to run-off. All sprayed plants were allowed to air dry prior to further handling. All fungicides were evaluated using the aforementioned method for their activity vs. all target diseases. Wheat leaf blotch and brown rust activity were also evaluated using track spray applications, in which case the fungicides were formulated as EC formulations, containing 0.1% Trycol 5941 in the spray solutions.
[00113] Wheat plants (variety Yuma) were grown from seed in a greenhouse in 50% mineral soil/50% soil-less Metro mix until the first leaf was fully emerged, with 7-10 seedlings per pot. These plants were inoculated with an aqueous spore suspension of Zymoseptoria tritici either prior to or after fungicide treatments. After inoculation the plants were kept in 100% relative humidity (one day in a dark dew chamber followed by two to three days in a lighted dew chamber at 20 °C) to permit spores to germinate and infect the leaf. The plants were then transferred to a greenhouse set at 20 °C for disease to develop. When disease symptoms were fully expressed on the Is leaves of untreated plants, infection levels were assessed on a scale of 0 to 100 percent disease severity.
Percent disease control was calculated using the ratio of disease severity on treated plants relative to untreated plants.
