Dearomatization of indole derivatives offers a straightforward approach to access diverse indolines. To date, the corresponding dearomative transformations involving electron-deficient indoles are limited. Herein, we report a one-electron strategy for dearomatization of electron-deficient indoles via a photoredox-catalyzed hydroalkylation employing commercially available glycine derivatives as the hydrofunctionalization
吲哚衍生物的脱芳香化作用提供了一种直接的方法来获得各种二氢吲哚。迄今为止,涉及缺乏电子的吲哚的相应脱芳香转换是有限的。在本文中,我们报告了一种单电子策略,用于通过使用可商购的甘氨酸衍生物作为加氢官能化试剂的光氧化还原催化的加氢烷基化来对缺电子的吲哚进行脱芳香化。随后进行DBU介导的内酰胺化,以独有的选择性,以良好或优异的收率获得了结构吸引人的内酰胺融合的二氢吲哚。
