Synthesis of pyrrolo[1,2-a]quinoxalines via copper or iron-catalyzed aerobic oxidative carboamination of sp3C–H bonds

Abstract

An aerobic oxidative carboamination of sp³C–H bonds with 2-(1H-pyrrol-1-yl)anilines has been developed. The oxidative carboamination processes utilized simple and readily available starting materials to produce pyrrolo[1,2-a]quinoxalines in good to moderate yields. The transformations also featured inexpensive metal catalysts (copper or iron) and a green oxidant (O₂).
