3-Amino-substituted saturated nitrogen heterocycles are an important subclass of β-diamines, appearing in a number of clinical agents. Herein, we report a unified approach to these products based upon the regioselective photoredox-mediated hydroamination of enecarbamates. The amine coupling partner can encompass diverse amine types under a single set of reaction conditions, including primary alkyl amines, ammonia, aryl and heteroaryl amines, and N?H heterocycles. The method enables the synthesis of a wide range of pharmaceutically relevant building blocks.
