regiospecific approach to 2- and 2,3-disubstituted indole derivatives in high yields via a one-pot aromatization driven dehydration pathway. This method allows a convenient preparation of diallyl indoles that are used as ring-closing metathesis (RCM) precursors for the orthogonal synthesis of pyrido[1,2-a]indoles and carbazoles. The synthetic utility of this method is illustrated by the synthesis of a microtubulin
以前未开发的将格利雅(Grignard)添加到羟吲哚中的方法通过一锅芳构化驱动的脱水途径,以高收率提供了一种区域特异性的方法,用于2-和2,3-二取代的吲哚衍生物。这种方法可以方便地制备用作烯丙基[1,2- a ]吲哚和咔唑的正交合成的闭环复分解(RCM)前体的二烯丙基吲哚。该方法的合成效用通过微管蛋白抑制剂和天然存在的咔唑生物碱的合成来说明。

We report a new Pd(II)-catalyzed C-H bond amination reaction to form carbazoles, an important motif that is prevalent in a range of systems. The catalytic amination process operates under extremely mild conditions and produces carbazole products in good to excellent yields. Carbazoles possessing complex moleculararchitecture can also be formed using this reaction, highlighting its potential in natural
