New synthetic procedures for the pyrrolo[2,3-b]indole skeleton have been developed via intramolecular annulation of indole derivatives under iodine(III). A series of indole derivatives with different protecting groups or substitutions were explored to facilitate the corresponding pyrrolo[2,3-b]indole compounds in excellent yields.
吡咯并[2,3- b ]吲哚骨架的新合成方法是通过在碘(III)下分子内吲哚衍生物的环化而开发的。研究了一系列具有不同保护基或取代基的吲哚衍生物,以促进其相应的吡咯并[2,3- b ]吲哚化合物的优异产率。
