The stereoselective synthesis of (2S, 3S, 7S)-3, 7-dimethylpentadecan-2-ol (diprionol) and its propionate, the sex pheromones of pine sawflies (Neodiprion sp. and other), in high enantiomeric purity was achieved from (1R, 3S)-2, 2-dichloro-3- methylcyclopropanecarboxylic acid. The carbon skeleton of diprionol was formed via copper- catalyzed cross-coupling reactions and diastereoselective methylation of the intermediate ...
