The invention discloses a synthetic method of
hyphantria cunea sex
pheromone components, and belongs to the technical field of
chemical production. (2S, 3R)-2, 3-
epoxy-1-tetradecanol is used as a rawmaterial, and the
hyphantria cunea sex
pheromone components (3Z, 6Z, 9S, 10R)-9, 10-
epoxy-3, 6-heneicosadiene and (3Z, 6Z, 9S, 10R)-9, 10-
epoxy-1, 3, 6-heneicosatriene are obtained through bromination,
coupling and hydrogenation. The process is mild and controllable in reaction, good in yield, simple and convenient to operate, few in reaction steps, low in production cost and suitable for large-scale production. The lure prepared from the sex
pheromone components synthesized by the synthesis method can effectively trap and kill a large number of
hyphantria cunea male moths in combination witha trap, is applied to hyphantria cunea pest situation forecasting and green prevention and control, and can reduce chemical
pesticide application, thereby reducing
pollution, protecting the environment and remarkably improving economic, social and ecological comprehensive benefits.
