A new approach to the synthesis of racemic analogs of 1, 5-dimethyl-branched insect pheromones from 4-methyltetrahydropyran

Ishmuratov,Yakovleva,Galyautdinova,Muslukhov,Tolstikov

, p. 740 - 744 (2007/10/03)

A new procedure was developed for the synthesis of racemic analogs of 1,5-dimethyl-branched insect pheromones based on monoalkylation of ethyl acetoacetate with 1-acetoxy-5-bromo-3-methylpentane produced upon decyclization of 4-methyltetrahydropyran.
