Organophotocatalytic dearomatization of indoles, pyrroles and benzo(thio)furans via a Giese-type transformation

open access: yesCommunications Chemistry, 2021
Dearomatisation of indoles allows efficient access to indolines, but often is incompatible with electron-withdrawing substituents. Here a photoredox Giese-type dearomatisation of indoles yields 2,3-disubstituted indolines bearing electron-withdrawing ...
