Based on the previously synthesized chiral intermediate, a new synthesis of pine sawfly pheromones bearing 3 stereocenters has been achieved. The key steps were Evans' template induction, Wittig olefina-tion, and conventional chemical operations. (2S,3S,7S)-3,7-Dimethylpentadecan-2-yl acetate and propanoate were obtained in 9 steps with an overall yield of 34%.
