Synthetic studies on vincorine are described; the conversion of 3-aminoethyl-3-alkyloxindoles to 3a,8a-dialkyl-1,2,3,3a,8,8a-hexahydropyrrolo[2,3-b]indoles has been achieved through an addition–cyclization sequence, and a fully functionalized key intermediate was constructed with this method.
介绍了对长春花碱的合成研究;通过加成-环化顺序,实现了 3-氨基乙基-3-烷氧基吲哚向 3a,8a-二烷基-1,2,3,3a,8,8a-六氢吡咯并[2,3-b]吲哚的转化,并用这种方法构建了全官能化的关键中间体。
