Simple synthesis method for sex pheromones of oriental fruit moths

The invention belongs to the field of chemical synthesis, and particularly relates to a simple synthesis method for sex pheromones of oriental fruit moths. The method includes subjecting 1,8-octandiolas a raw material to unilateral bromination reaction to obtain 8-bromooctanol, reacting the 8-bromooctanol with triphenylphosphine to obtain 8-hydroxyoctyl triphenylphosphonium salt, subjecting the 8-hydroxyoctyl triphenylphosphonium salt and n-butanal to Wittig reaction under the action of an alkali to obtain (Z/E)-8-dodecene-1-alcohol, and performing acetylation under the action of pyridine andacetic anhydride to obtain a target product. The cis-trans ratio of enol obtained after the Wittig reaction ranges from 91.8:8.2 to 92.9:7.1; within the optimal attraction range, and by strictly controlling the amount of the acetic anhydride, the properly proportioned sex pheromones of the oriental fruit moths can be obtained according to a 'one-pot' method.

Use of enyne compounds in the synthesis of insect pheromones

A new approach has been developed to the synthesis of monogenic insect pheromones with acetogenin and macrolide structures, using the low reactivity of ozone and of 9-borabicyclo[3.3.1]nonane towards an acetylenic function as compared with a vinyl function.
