Summary:
the present invention discloses a synthesis method of peach borer sex pheromone (Z,E)10 hexadecenal compound, & omega; Bromodecanol and dihydropyran under the action of a catalyst to obtain the corresponding acetal, acetal and trialkyl phosphite/aryl ester to generate acetal phosphonic acid dialkyl/aryl ester, acetal phosphonic acid dialkyl/aryl ester reacts with n-hexanal, (Z,E)10 hexadecene 1 alcohol with type E is generated, and (Z,E)10 hexadecene 1 alcohol with type E is oxidized with oxidant to obtain (Z,E)10 hexadecene aldehyde with type E. The method of the invention has few side reactions and high product purity.

Summary:
[Objective] To synthesize the sex pheromone of peach borer by Wittig reaction-cis, trans -10-hexadecenal. [Method] Using dimethyl sulfoxide sodium salt as base and anhydrous dimethyl sulfoxide (DMSO) as solvent, the target was synthesized by Wittig reaction at a temperature of 20~25 ℃. [Results] 1.2g peach borer sex pheromone-cis and trans -10-hexadecenal was synthesized by Wittig reaction with a yield of 30% and cis/trans of 20/80. The field lure test showed that the synthesized compound had the best lure effect on peach borer at 50 μg/lure dose. [Conclusion] The sex pheromone of peach borer synthesized by Wittig reaction can be directly used for field control without cis-and inverse proportional transformation.
