Herein, we demonstrated Mn-catalyzed selective C-3 functionalization of indoles with alcohols. The developed catalyst can also furnish bis(indolyl)methanes from the same set of substrates under slightly modified reaction conditions. Mechanistic studies reveal that the C-3 functionalization of indoles is going via a borrowing hydrogen pathway. To highlight the practical utility, a diverse range of substrates
在此,我们展示了 Mn 催化的吲哚与醇的选择性 C-3 官能化。开发的催化剂还可以在稍微改进的反应条件下从同一组底物提供双(吲哚基)甲烷。机理研究表明,吲哚的 C-3 官能化是通过借氢途径进行的。为了突出实用性,合成了多种底物,包括九种结构上重要的药物分子。此外,我们还介绍了一种一锅级联策略,用于直接从 2-氨基苯基乙醇和酒精合成 C-3 官能化吲哚。
