Abstract

The sex pheromone of Grapholitha molesta, (Z/E)-8-dodecylen-1-ol acetate, was easily synthesized in an overall yield of 41.5% with 1,8-octanediol as starting material via mono-esterification, PCC oxidation, and Witting reactions. The Z/E ratio is 83:17. Configuration transformation of Z/E 83:17 compound with sodium nitrite and nitric acid resulted in the production of a compound with Z/E 24:76. The products were confirmed by IR, 1H NMR, and MS spectral data.
