A rapid stereocontrolled synthesis of the 3a-hydroxy-pyrrolo[2,3-b]indole skeleton, a building block for 10b-hydroxy-pyrazino[1′,2′:1,5]pyrrolo[2,3-b]indole-1,4-diones

A two-step selenocyclisationâoxidative deselenation sequence was used to establish the 3a-hydroxy-pyrrolo[2,3-b]indole core; these tricycles were used as effective precursors to 10b-hydroxy-pyrazino[1â²,2â²:1,5]pyrrolo[2,3-b]indole-1,4-diones.
采用两步硒杂环化-氧化脱硒序列构建了3a-羟基吡咯并[2,3-b]吲哚核心;这些三环化合物被用作高效前体,转化为10b-羟基吡嗪并[1′,2′:1,5]吡咯并[2,3-b]吲哚-1,4-二酮。
