PREPARATION OF GOSSYPLUREAND 1-METALLO-5,9-TETRADECADIENE

摘要

Process for the production of the insect sex attractant, gossyplure, is provided. The process comprises first disproportionating 1,5-cyclooctadiene and 1-hexene to give 1,5,9-tetradecatriene, then metallating the triene to form a 1-metallo-5,9-tetradecadiene, and finally treating the organometal compound with a C2-synthon to give directly 7,11-hexadecadienyl acetate or a substituted 7,11-hexadecadienyl moiety which can readily be converted to the desired acetate.
