We describe efficient and flexible enantioselective syntheses of the active enantiomers of the pheromones of pine sawflies, including the species Diprion jingyuanensis, their homologs and, stereoisomers, as well as those identified from the Chinese species Diprion jingyuanensis, i.e., 126. A total of 48 compounds, including acetates 78–101 and propanoates 102–125, have been synthesized. Our general

Abstract Based on the previously synthesized chiral intermediate, a newsynthesis of pinesawflypheromones bearing 3 stereocenters has been achieved. The key steps were Evans’ template induction, Wittig olefination, 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%.
摘要 在前人合成的手性中间体的基础上,实现了一种新的含3个立体中心的松叶蜂信息素的合成。关键步骤是 Evans 的模板诱导、Wittig 烯化和常规化学操作。(2 S ,3 S ,7 S )-3,7-二甲基十五烷-2-乙酸酯和丙酸酯分9步得到,总收率为34%。
