    Research progress on the asymmetric syntheses of sex pheromones of loopers

    • Loopers are common pests of fruit trees and forests, and their sex pheromone components include chiral methyl-branched alkanes, trienes and chiral epoxy olefins. The sex pheromone of loopers can be used for attracting males and monitoring the seasonal activities as a promising technology. The syntheses of the chiral methyl-branched alkanes involved chiral sources, enzymatic kinetic resolutions, asymmetric catalytic reactions, chelation-controlled reactions and chiral inductions, which were described on the basis of the constructions of chiral center. Furthermore, according to the linking strategies of key intermediates, the preparation of chiral epoxy olefins, such as alkylative epoxide rearrangement, the reaction of alkynyl lithium reagent and the use of Gilman reagents, was reviewed.
