represents. ] Allethrin is known as a useful pesticide.
Invented by MS Schechter in 1949, it is widely used throughout the world due to its excellent insecticidal activity and low toxicity, and various studies have been conducted on its synthesis methods. Among these, various proposals have been made regarding methods for synthesizing the alcohol component of allethrin, some of which have been incorporated into actual production. However, these methods are not necessarily industrially satisfactory in terms of yield, operation, environmental problems, etc. For example, the method for synthesizing allethrone that is currently practiced industrially is a slight improvement on the method first carried out by MS Schechter et al., and consists of the following steps. However, in this method, the final step from compound (4) to arethrolone (5) has a low yield;
There are drawbacks such as the difficulty and high cost of synthesizing methylglyosazar (6) used in the synthesis of compound (4) from compound (3), and this method is not necessarily satisfactory industrially. do not have. In addition, as a method for synthesizing arethrolone using the Michael reaction, there is a method by RH Schlessinger et al. This method uses methylthioacetone (7) and ketene thioacetal monooxide (8) as raw materials and consists of the following steps. . However, the method of Schlessinger et al. also has the following major problems as an industrial method. After the Michael reaction, allyl iodide, which is highly reactive and expensive, is used to introduce an allyl group into the α-position of the sterically crowded ketone. (Process of compound (9) → (10)) In the reaction from compound (11) to arethrolone (5),
For industrial use, potassium t-butoxy is used, which is highly dangerous and difficult to handle. Therefore, this method is not necessarily satisfactory as an industrial manufacturing method. Against this background, the present inventors investigated cyclopentenolones used as intermediates for insecticidal compounds, particularly those of the formula () As a result of intensive research into the method for producing the cyclopentenolone compound shown in Completed the invention. That is, the present invention provides a novel aldehyde compound represented by the general formula () and a method for producing the same. (In the formula, R 1 represents the same meaning as above, and R 3 represents an alkyl group having 3 or less carbon atoms.) The present invention provides a method for producing a novel aldehyde compound represented by formula (). The compound of the present invention represented by the general formula () can be easily and efficiently converted into a cyclopentenolone compound represented by the formula (), which is a useful intermediate for agricultural chemicals, by treatment with a base, It is an extremely useful intermediate. Furthermore, the acetal compound represented by the general formula () is a new product, for example, the acetal compound represented by the general formula () (wherein, R 1 has the same meaning as above) is reacted with a nitroolefin represented by the formula () CH 3 −CH=CH−NO 2 () in the presence of a base, and the compound represented by the general formula () It can be easily obtained by leading to a nitro compound represented by , then treating this with a base, and then treating it with an acid in a lower alcohol having 3 or less carbon atoms. In the compound of the present invention represented by the general formula (), specific examples of R 1 include, for example, a phenyl group,
Examples include p-tolyl group. When producing the compound of the present invention represented by the general formula (), an acetal compound represented by the general formula () is reacted with an acid such as a mineral acid such as hydrochloric acid or sulfuric acid or a lower fatty acid such as acetic acid in the presence of water. The desired aldehyde compound can be obtained in good yield by hydrolysis. Although a solvent is not particularly required, a mixture of solvents such as benzene, toluene, hexane, tetrahydrofuran, methanol, and ethanol can be used. The reaction temperature is not particularly limited, but −60
It can be carried out in the range of .degree. C. to 60.degree. C., preferably in the range of -30.degree. C. to 30.degree. The reaction time depends on the solvent used,
It varies depending on the reaction temperature, acid, etc., but in most cases it takes 5 minutes or more.
It can be done in 3 hours. In the method of leading to a cyclopentenolone compound by the method described above via the compound of the present invention represented by the general formula (), a propargyl group can be introduced before the Michael reaction, so it is extremely easy to introduce a propargyl group. It has the advantage of being able to be used in many ways. Furthermore, in the process of treating the compound represented by the general formula () with a base to synthesize the final target compound, a cyclopentenolone compound represented by the formula (), a general-purpose base such as sodium ethylate can be used with good yield. It is advantageous as an industrial production method compared to the method of RH Schlessinger et al., and it is not used industrially today because the yield of the ring-closing reaction step is good and methylglyoxal is not used. It has many advantages compared to the method of MSSchechter et al. As described above, the present invention relates to a novel intermediate extremely useful in the production of agricultural chemicals, and a method for producing the same, and is useful for the industrial production of these products by reducing the number of steps, ease of operation, and yield. Its contribution, such as the merits of this technology, is enormous. EXAMPLES Next, in order to make the present invention more clear, the present invention will be explained in detail using the following examples, but it goes without saying that the present invention is not limited thereto.
