Method for synthesizing Metconazole epoxidation intermediate

The invention discloses a method for synthesizing a Metconazole epoxidation intermediate. The method comprises the steps: performing a reaction on trimethylsulfur halide or trimethyl sulfoxide halideand alkaline in a corresponding solvent under the condition of a catalyst so as to produce sulfur ylide, then adding 2,2-dimethyl-5-(4-chlorobenzyl)cyclopentanone, performing a Corey-Chaykovsky reaction, adding water and ethyl acetate for extraction after completion of the reaction, evaporating the organic phase until dryness, and recrystallizing the crude product so as to obtain the Meconazole epoxidation intermediate. According to the method for synthesizing the Metconazole epoxidation intermediate, epoxidation of carbonyl groups on cyclopentanone in the raw materials is performed through adoption of a catalyst for the Corey-Chaykovsky reaction and selection of a suitable solvent so as to achieve a satisfactory implementation effect, the epoxidation reaction time is shortened significantly, the conversion rate is improved, and the catalyst is cheap and easily available; and the method is suitable for industrial production.
