The first enantioselective synthesis of (2R,13R,8Z)-2,13-diacetoxy-8-heptadecene 1, the major component of the sex pheromone of the pear leaf midge, Dasineura pyri, has been achieved. The key steps include the (R,R)-BINOL/Ti(OiPr)(4) catalyzed alkynylzinc addition to an unsaturated aldehyde, the ring opening of the chiral epoxide with a Grignard reagent, and the partial reduction of an acetylenic diol ester to a (Z)-olefinic diol ester with hydrogen and P2-Ni.
