Abstract
The synthesis of 7(E), 9(Z)-dodecadien-1-yl acetate using for the olefination steps Wittig and Horner reactions under phase transfer conditions is reported. The 7(E) double bond was prepared by Horner coupling of 7-tert-butoxy-heptanal (1) with 0,0-diethylphosphonoacetate (2) in a two phase system. Wittig olefination was used to build up the 9(Z) double bond by reacting 9-tert-butoxy-2-nonen-1-yl-triphenyl-phosphonium bromide(13) with propionaldehyde under phase transfer catalytic conditions.
