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.

The fall webworm, Hyphantria cunea, is a significant worldwide pest, and its sex pheromone includes two alkenals and three epoxy olefins, which can be used to trap H. cunea and monitor population dynamics, and have a promising application. According to the synthesis of aldehyde, the preparations of alkenals include biomimetic synthesis, Weinreb amide method, enzyme catalyzed reaction, iridium-catalyzed hydrosilylation of esters, or cobalt-catalyzed hydrosilylation of esters; whereas on the basis of the linking approaches of key intermediates, the synthetic methods of epoxy olefins, such as thiocyanatocuprate method, Wittig coupling, alkynyl lithium reagent substitution, Gilman reagent substitution and alkylative epoxide rearrangement, were summarized.
