Concisetotalsyntheses of four members of the dolabellane family of diterpenoid natural products are reported. Key features of the developed route include the first demonstration of an enantioselective, intramolecular Type I Diels-Alder macrobicyclization, the first example of a stereoselective pi-allyl Stille coupling reaction involving a farnesyl-derived intermediate, a powerful new reagent for
报道了二萜类天然产物的多拉标烷家族的四个成员的简明全合成。所开发路线的主要特点包括首次展示了对映选择性、分子内 I 型 Diels-Alder 大环化,这是立体选择性 pi-allyl Stille 偶联反应的第一个例子,涉及法呢基衍生的中间体,这是一种用于形成二噻烷的强大新试剂具有酸敏感分子,以及基于改进的沃尔夫光化学重排的独特且高效的环收缩序列。
