alkyl p-tolyl sulfones with dimethyl disulfide could be easily hydrolyzed by CuCl2–SiO2 to give the corresponding ketones in fairly good yields. This method was applied to the synthesis of DouglasFir Tussock Moth Pheromone.
Synthesis of<i>cis</i>-12-Nonadecen-9-one,<i>cis</i>-13-Icosen-10-one, the Pheromone of Peach Fruit Moth, and<i>cis</i>-15-Henicosen-11-one, the Pheromone of Douglas Fir Tussock Moth
A convenient synthesis of cis-12-nonadecen-9-one (4a), cis-13-icosen-10-one (4b), the pheromone of peach fruit moth, and cis-15-henicosen-11-one (4c), the pheromone of Douglasfirtussockmoth, is described. 4a was synthesized from methyl 3-oxoundecanoate and 1-bromo-2-nonyne (2a) via 12-nonadecyn-9-one. The higher homo-log 4b could be obtained from methyl-3-oxododecanoate and 2a. Similarly, 4c was

Both (Z)-6-heneicosen-11-one, the pheromone of Douglas fir tussock moth, and (Z)-8-dodecenyl acetate, the pheromone of oriental fruit moth, have been synthesized from cyclohexane-1,3-dione.
