Copper‐Catalyzed Aerobic Oxidative Amination of Indole Derivatives <i>via</i> Single‐Electron Transfer

Abstract

Abstract An efficient and clean approach for the oxidative amination of indole derivatives with phenothiazines is developed under copper‐catalyzed aerobic conditions. The reaction is carried out vi a the cross‐coupling of indole radical cation and phenothiazine radical in air. This approach offers a new perspective in the application of phenothiazine as a nitrogen group source for C−N bond formation reactions.
