Abstract: Oleyl alcohol was used as a starting material and converted into oleyl tosylate with tosyl chloride and pyridine. By reduction of this tosylate with lithium aluminium hydride and then ozonization, the intermidiate 1-nonanal was obtained. (Z)-9-tricosene was (Z)-stereoselectively prepared by Wittig reaction of 1-nonanal with lithium salt-free phosphorus ylide generated from the reaction of n-tetradecyltriphenylphosphonium bromide and sodium bis(trimethylsilyl)amide.

Key words: Insect sex pheromone, (Z)-9-tricosene, Wittig reaction, Ozono-lysis, Synthesis
