Peach twig borer is one of the most serious pests, whose sex pheromone is 5E-decen-1-ol and 5E-decenyl acetate. Synthesis of both compounds was achieved from acrolein. Firstly, a tandem addition reaction of acrolein with acetylene in the presence of Pd(OAc)2 gave 5-bromo-4E-pentenal, which reacted with the ylide prepared from (methoxymethyl)triphenyl- phodphonium chloride to afford (1E,5E/Z)-1-bromo-6-methoxyhexadiene. The compound was coupled with Grignard reagent, followed by hydrolysis and reduction to give 5E-decen-1-ol. Esterification of the alcohol afforded 5E-decenyl acetate.

Key words: peach twig borer, 5E-decen-1-ol, 5E-decenyl acetate, pheromone synthesis, Kumada cross-coupling
