stereoselective asymmetric boronic ester chemistry has been used to install all three chiral centers in a convergent synthesis of highly pure stegobinone, the epimerically labile pheromone of the drugstore beetle, Stegobium paniceum, and the furniture beetle, Anobium punctatum. Asymmetric centers were installed via the reaction of (dichloromethyl)lithium with 1,2-dicyclohexylethane-1,2-diol boronic esters. The
高度立体选择性的不对称硼酸酯化学已被用于将所有三个手性中心安装在高纯度 stegobinone、药店甲虫 Stegobium paniceum 和家具甲虫 Anobium punctatum 的差向不稳定信息素的会聚合成中。通过(二氯甲基)锂与 1,2-二环己基乙烷-1,2-二醇硼酸酯的反应安装不对称中心。合成策略利用常见的(α-氯代烷基)硼酸酯中间体作为两个片段和目标分子所有不对称性的来源。这两个部分通过羟醛缩合连接并转化为 stegobiol,这是 S. pananeum 信息素的次要成分,可能是 stegobinone 的生物遗传前体。Stegobiol 稳定且易于纯化,
