Indoles, especially multisubstituted ones, are privileged scaffolds found widely in natural products, bioactive molecules, fine chemicals, and organic functional materials. Although several intramolecular electrochemical cyclization reactions of vinyl anilines to construct indoles have been reported in recent years, the intermolecular process between simple anilines and other readily available synthons
吲哚,尤其是多取代的吲哚,是广泛存在于天然产物、生物活性分子、精细化学品和有机功能材料中的特殊支架。尽管近年来已经报道了几种乙烯基苯胺的分子内电化学环化反应以构建吲哚,但简单苯胺和其他容易获得的合成子之间的分子间过程尽管占主导地位,但仍然相对未开发。在此,我们报告了苯胺和市售 1,3-二羰基化合物的分子间电氧化环加成反应。该方法为在没有过渡金属催化剂或外部化学氧化剂的情况下合成广泛的多取代吲哚提供了替代途径。
