A redox amination strategy was developed for the synthesis of N-aryl-1-aminoindoles by N–N bond formation. Reaction of nitrosobenzenes with readily available indolines using Brønsted acid catalysis allows N–N bond formation under mild conditions. This method exploits the inherent reducing power of indoline to synthesize biologically relevant molecular architectures via redox amination. A one-pot synthesis of 1-aminoindoles starting from simple aniline and indolines is likewise described.
我们开发了一种氧化还原胺化策略,通过 N-N 键的形成合成 N-芳基-1-氨基吲哚。利用布伦司特酸催化亚硝基苯与现成的吲哚啉反应,可以在温和的条件下形成 N-N 键。这种方法利用了吲哚啉固有的还原能力,通过氧化还原胺化合成与生物相关的分子结构。此外,还介绍了从简单的苯胺和吲哚开始的 1-氨基吲哚的单锅合成法。
