Abstract

The invention belongs to the technical field of chemical production, and particularly relates to a novel method for synthesizing sex pheromone components of hyphantria cunea, and the sex pheromone components of hyphantria cunea comprise I [(3Z, 6Z, 9S, 10R)-9, 10-epoxy-3, 6-heneicosa diene ] and II [ (3Z, 6Z, 9S, 10R) -9, 10-epoxy-1, 3, 6-henesa triene ]. Carbon tetrabromide and triphenylphosphine are used to mildly perform bromination reaction on the key intermediate (2S, 3R) -2, 3-epoxy-1-tetradecanol (compound 1) , and the method is simple, convenient and high in yield; according to the invention,1, 4-heptadiyne and 1-heptene-3, 6-diyne are introduced into related structural fragments, so that the reaction steps are reduced, and the reaction yield is improved; and according to the method, the use of the Lingdeler palladium catalyst is abolished, and the P2-type nickel generated in situ by nickel acetate and sodium borohydride is used as the catalyst, so that the production cost is reduced, excessive hydrogenation of carbon-carbon triple bonds is prevented, the reaction is mild and controllable, and the yield is good.

Description

technical field

[0001] The invention relates to the technical field of chemical production, in particular to a method for synthesizing a novel sex pheromone component of the white moth. Background technique

[0002] American white moth, also known as American lamp moth, autumn curtain caterpillar, autumn curtain moth, belongs to Lepidoptera, Dilipidae, is a world-renowned quarantine pest, mainly harming fruit trees, street trees and ornamental trees, especially broad-leaved trees. , causing serious harm to garden trees, economic forests, farmland shelterbelts, etc., and has been included in the first batch of invasive alien species in my country.

[0003] American white moth is a kind of leaf-eating pest that seriously harms many kinds of plants. Its harmful characteristics are: first, it has miscellaneous feeding habits and can harm many kinds of plants including forest trees, fruit trees, crops, and flowers; second, it has strong reproductive ability. Three generations of ...
