The stereo- and enantioselective synthesis of the yellow scale pheromone, (S)-(-)-3,9-dimethyl 6-(1-methylethyl) (E)-5,8-decadien 1-ol acetate, from 3-(R)+)-valerolactone and [(4-methyl 3-pentenyl) sulfonyl] benzene is described. The key step is the introduction of the isopropyl group by the stereoselective cross-coupling reaction of the dienesulfone with isopropylmagnesium chloride in the presence
