A Stereoselective Synthesis of a cis, cis Conjugated Dienol, a Candidate Pheromone

Abstract

There has been much interest recently focussed on the synthesis of geometrically pure conjugated diene alcohols, aldehydes and esters useful as sex pheromones and candidate sex attractants.^1,2 A recent communication³ on the synthesis of all four geometrical isomers of some conjugated dienols by four different Wittig reactions prompts us to report our results on the synthesis of a cis, cis conjugated dienol, as the reported synthesis of this type of isomer yielded product of low geometrical purity.³ We describe below our stereo-selective synthesis of a cis, cis conjugated dienol
