Abstract: The sex pheromone of grapholitha molesta 8(Z/E)-dodecen-1-ol acetate (6) was synthesized bYUsing oleic acids as the raw material. 1,8(Z)-Heptadecadiene (2) was obtained from the decarbonylation reaction of oleic acid (1) in the presence of palladium complexes catalyst. Selective hydroboration and oxidation of 2 by Ca(BH422O2 system gave 8(Z)-heptadecen-1-ol (3), which then was acetylized by treatment with Ac 2O/pyridine to afford 8(Z)-heptadecen-ol acetate(4). The compound 4 was ozonized to form the keYINtermediate 8-acetoxyoctanal (5), then compound 5 was coupled with the Wittig regents to obtain the title compound 8(Z/E)dodecen-1-ol acetate (6), Z/E molar ratio is 25;75. The overall yield was 45%. The structures of all the compounds were confirmed by IR, MS and NMR spectra.

Key words: Sex pheromone, Oleic acid, Hydroboration, Ozonization, Wittig reaction
