Exo- and Endohormones. X. A Novel Route to an Isomer Mixture of 7,9-Dodecadien-1-yl Acetate Utilizable in Field Attraction of Lobesia botrana Males

Wittig condensation of (Z)-2-pentenylidene triphenylphosphorane (14) and 7-tert.-butoxy-heptanal (13) under conditions of phase transfer catalysis and subsequent conversion into the corresponding acetate afforded a mixture of 28percent 7(E),9(Z)-dodecadien-1-yl acetate, the sex pheromone of Lobesia botrana, along with the other geometrical isomers and 30percent unidentified by-products.The synthons 14 and 13 were prepared starting with (Z)-2-butene-1,4-diol (1) and hexane-1,6-diol (9), respectively.
