The sex pheromone of the cabbage looper Trichoplusia ni Hubner, (Z)-7-dodecen-1-yl acetate, was synthesized via a bimolecular nucleophilic substitution reaction between the Grignard reagent of the protected bromohydrin with (Z)-2-hepten-1-yl acetate in the presence of CuI catalyst as a key step. An efficient synthetic method of preparation of the pheromone was achieved from (Z)-2-butene-1,4-diol in four steps with an overall yield of 22.1%.
