Compound of thioketal, synthetic method, and application in synthesizing pheromone of southern Diabrotica in optical purity

Abstract

This invention relates to a method for synthesizing novel chain molecules with thioketal structure, which can be used to synthesize optical pure sex pheromone of Diahrotica undecimpunctata (R)-10-methyl-2-tridecanone. The method has such advantages as few steps, easy operation and high yield.

Description

technical field The invention relates to a class of thioketal compounds and their synthesis method, which can be used to synthesize optically pure southern corn rootworm sex pheromone (R)-10-methyl-2-tridecanone. The method of the invention is used to synthesize the optically pure southern corn rootworm sex pheromone (R)-10-methyl-2-tridecanone, which has shorter steps, simpler operation and higher yield than the method in the existing literature. technical background The superfamily Diabroticites, belonging to the order Coleoptera, includes a wide variety of pest groups that damage field crops. Both adults and larvae are herbivorous, feeding on roots, stems, leaves, flowers, etc. of plants. Many species cause serious harm to crops, vegetables, forest trees, fruit trees, and pastures. For example, the world-renowned pest potato beetle belongs to the Chrysophyte family. The larvae of various types of beetles seriously damage corn crops, such as the Southern cornrootworm (Di...

Problems solved by technology

In 1982, Guss et al. successfully identified and synthesized a western corn rootworm sex pheromone: propionate-8-methyl-2-n-decyl ester, which is effective against western corn rootworm, northern corn rootworm and Mexican corn rootworm. Male adults are very attractive, but less so to southern corn rootworms (J. Chem. Ecol. 1982, 8, 545)
