Four pheromone components of the female painted apple moth (Teia anartoides), an Australian insect pest, were synthesized. These were (Z)-6-henicosen-11-one (1),(6 Z, 8 E)- 6, 8-henicosadien-11-one (2),(Z)-cis-9, 10-epoxy-6-henicosene (3), and (Z)-cis-9, 10-epoxy- 6-icosene (4). 2-Dodecanone was converted to 1 and 2, and both the enantiomers of 3 and 4 were synthesized from the enantiomers of 4-tert-butyldimethylsilyloxy-cis-2, 3-epoxy-1- ...
