An efficient synthesis of (3Z,6Z)‐cis‐9,10‐epoxy‐3,6‐henicosadiene (1), the major component of sex pheromone of saltmarsh caterpillar moth Estigmene acrea (Drury), was accomplished from commercially available pentadec‐3‐yn‐1‐ol and bromoundecane. Chirality was introduced by employing Sharpless asymmetric dihydroxylation on cis‐olefin intermediate in the synthesis of 1, for the first time. The other
有效地合成了(3 Z,6 Z)-顺式9,9,10-环氧-3,6-二十二碳二烯(1)(盐沼毛虫蛾Estigmene英亩(Drury)性信息素的主要成分)。 pentadec-3-yn-1-ol和bromoundecane。首次在1的合成中通过对顺式烯烃中间体进行Sharpless不对称二羟基化反应引入了手性。其他关键反应包括金属溶解偶联,Lindlar的催化剂辅助部分加氢,一锅,邻位二醇的三步环氧化和Wittig烯烃化。总产量1在八个步骤中为24.7%。这种合成方法的效率和简便性使信息素1可以在有害生物管理程序中潜在使用。
