Abstract: Polymer-bound 3-benzyloxypropane-1,2-diol 2 was used for the protection of 2,6-haptanedion 3. 3,7-Dimethyl-2,7-octadien-1-yl propanoate la, lb,the main component ofSan Jose scale's sex pheromone was obtained in 34.8% yield by Wittig reaction. Theproduct has a Z:E isomer ratio of 18.8% to 81.2%

Key words: polymer-supported reagent, Witting reaction, dimethyl octadienyl propionate, sex-attracting pheromone, synthesis
