Synthesis of (S,E)-1-Methyl-9-dodecenyl Acetate,the Sex Pheromone of the Hessian Fly,Mayetiola destructor,by Lipase-catalyzed Enantioselective Hydrolysis

(S,E)-1-Methyl-9-dodecenyl acetate [(S)-8], the sex pheromone of the hessian fly, Mayetiola destructor, was synthesized in a highly enantiomerically pure form by Pseudomonas cepacia lipase-catalyzed hydrolysis.
