Conventionally, a method for synthesizing chrysanthemum acid derivatives having a polyhalomethyl group at the olefin moiety is a method of adding polyhaloethane to ethyl 3,3-dimethyl-4-pentenoate, followed by cyclization and dehydrohalogenation (JP-A-Sho et al. 53-95945), () Method of synthesis from 1-polyhalomethyl-1-chloro-4-methyl-1,3-pentadiene and diazoacetic acid ester (JP-A-53-95945), ()2-{2,2- A method using a ring reduction reaction of dichloro-2-(polyhalomethylethyl)}-2-chloro-3,3-dimethylcyclobutanones (Japanese Patent Application Laid-Open No. 56-92830) is known. However, although the method () is effective for the synthesis of a limited number of chrysanthemum acid derivatives, it is often difficult to obtain polyhaloethane as a raw material. ()
Both of the methods (2) and (2) have the disadvantage that the synthesis of raw materials is complicated and is difficult to implement industrially. [Object of the Invention] The present inventors have conducted extensive studies on a method for industrially synthesizing chrysanthemum acid derivatives having a polyhalomethyl group at the olefin moiety by overcoming the drawbacks of such conventional methods. It has been revealed that the cyclopropane derivative represented by the general formula [] is extremely useful as a synthetic raw material, and the present invention has been completed. [Structure of the Invention] The cyclopropane derivative represented by the general formula [] of the present invention can be produced according to the following reaction formula. (In the formula, R 1 is an alkyl group or an aryl group,
R 2 ' is a silyl group, and X is a halogen atom. ) [Step A] This step is to react the 2-formyl-3,3-dimethylcyclopropanecarboxylic acid ester represented by the general formula [] with the polyhalobinylsilane represented by the general formula [] to obtain the general formula []. A cyclopropane derivative represented by formula [-a] is produced. 2-formyl- represented by the general formula [] which is the raw material for this step
3,3-dimethylcyclopropanecarboxylic acid ester is a compound that can be easily and quantitatively produced by ozonolysis of ordinary chrysanthemum acid derivatives, such as ethyl 2-formyl-3,3-dimethylcyclopropanecarboxylate, 2-formyl-3,3-
t-butyl dimethylcyclopropanecarboxylate,
Phenyl 2-formyl-3,3-dimethylcyclopropanecarboxylate, Benzyl 2-formyl-3,3-dimethylcyclopropanecarboxylate, 2-
3-Phenoxyphenylmethyl formyl-3,3-dimethylcyclopropanecarboxylate, cyano(3-phenoxyphenyl)methyl 2-formyl-3,3-dimethylcyclopropanecarboxylate, 2
-Formyl-3,3-dimethylcyclopropanecarboxylic acid pentafluorophenylmethyl, etc. can be used. The other raw material, polyhalovinylsilane, was obtained by reacting the corresponding vinyllithium with chlorosilane (J.Org.Chem., 33 , 472
(1968); Tetrahedron Lett., 24 , 5615 (1983);
Chem.Lett., 1765 (1984)), etc., and examples include (triethylsilyl)trifluoroethylene, (dimethylphenylsilyl)trifluoroethylene, (benzyldimethylsilyl)trifluoroethylene, 1- Triethylsilyl-1-chlorodifluoroethylene, 1
-dimethylphenylsilyl-1-chlorodifluoroethylene, etc. can be used. In this step, 2-formyl-3,3-dimethylcyclopropanecarboxylic acid ester and polyhalovinylsilane are first reacted in the presence of a fluorine anion source. Fluorine anion sources include tris(diethylamino)sulfonium difluorotrimethylsilicate (TASF), tetrabutylammonium fluoride, cesium fluoride, potassium fluoride, etc., as long as they can generate fluorine anions under anhydrous conditions. All can be used. A so-called catalytic amount is sufficient for the amount used. The reaction is preferably carried out in a suitable solvent, and for example, ether solvents such as diethyl ether, tetrahydrofuran (THF), and 1,4-dioxane, and amides such as dimethylformamide and hexamethylphosphoric triamide can be used. The reaction proceeds at -50°C to 100°C, but preferably -20°C to 50°C for efficient reaction. [Step B] In this step, the cyclopropane derivative represented by the general formula [-a] is solvolyzed using a protic solvent in the presence of an acid to produce the cyclopropane derivative represented by the general formula [-b]. It is something. In this step, solvolysis is carried out using a protic solvent in the presence of an acid. As the acid, for example, mineral acids such as hydrochloric acid and sulfuric acid, and organic acids such as p-toluenesulfonic acid, methanesulfonic acid, and trifluoroacetic acid can be used. Protic solvents include methanol, ethanol, t-butyl alcohol,
Alcohols such as ethylene glycol or water can be used, and these may be used in combination. The reaction proceeds at -50°C to 100°C, but preferably 0°C to 30°C for efficient reaction. [Step C] In this step, 2-formyl-3,3-dimethylcyclopropanecarboxylic acid ester represented by the above general formula [] is reacted with trifluorovinyl lithium to form a cyclopropane carboxylic acid ester represented by the above general formula [-b]. This is to produce propane derivatives. The 2-formyl-3,3-dimethylcyclopropanecarboxylic acid ester represented by the above general formula [], which is a raw material for this step, is an easily available compound as described in the above [A step], and for example, the above [A
[Step] can be used. The other raw material, trifluorovinyllithium, is also a compound that can be easily synthesized from trifluoroethylene or chlorotrifluoroethylene (J.
Org.Chem., 33 , 472 (1968); Tetrahedron
Lett., 24 , 5615 (1983); Chem. Lett., 1765
(1984)). This step is preferably carried out in a solvent, and ether solvents such as diethyl ether and THF can be used alone or in a suitable mixture with hydrocarbon solvents such as hexane and pentane. The reaction proceeds at -150°C to -50°C, but from the viewpoint of efficiency and yield, it is preferably carried out at -135°C to -70°C. Hereinafter, the present invention will be explained in more detail with reference to Reference Examples and Examples. Example 1 Ethyl 2-formyl-3,3-dimethylcyclopropanecarboxylate (cis-trans mixture)
Add 0.1 ml of TASF (1M THF solution) to a solution of 175 mg (1.03 mmol) and 240 mg (1.22 mmol) of triethylsilyltrifluoroethylene in 2 ml of THF at 0°C.
(0.1 mmol) was added dropwise at 0℃ for 1 hour, then at room temperature for 10 minutes.
Stir for hours. After filtering off the catalyst using a silica gel sulfate column, the mixture was concentrated under reduced pressure to obtain a crude product. 2-(1) was purified by thin layer chromatography (silica gel, hexane-dichloromethane 1:1)
22 mg of cis form and 75 mg of trans form of ethyl -triethylsiloxy-2,3,3-trifluoro-2-propenyl)-3,3-dimethylcyclopropanecarboxylate were obtained. Total yield 39%. Cis form (mixture of two stereoisomers (7:3))
