Abstract

Abstract 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 28% 7 (E), 9 (Z)-dodecadien- 1-yl acetate, the sex pheromone of Lobesia botrana, along with the other geometrical isomers and 30% unidentified by-products. The synthons 14 and 13 were prepared ...
