Hexahydropyrrolo[3,4-b]indoles 6, 10, and 13 are obtained from 2-bromo-3-carboxamides 5, 9, and 12, respectively, by a 1,5-radical translocation process followed by 5-endo-trig cyclization to the indole C-2 position.
六氢吡咯并[3,4-b]吲哚 6、10 和 13 分别由 2-溴-3-甲酰胺 5、9 和 12 通过 1,5-自由基易位过程和 5-endo-trig 获得环化至吲哚 C-2 位。
