a synthetic challenge because of the remote and unactivated nature of β-C–H bonds in these motifs. Herein, we demonstrate the β-functionalization of saturated aza-heterocycles enabled by a two-step organic photoredoxcatalysis approach. Initially, a photoredox-catalyzed copper-mediated dehydrogenation of saturated aza-heterocycles produces ene-carbamates. This is followed by an anti-Markovnikov hydrofunctionalization
