A merger of organocatalysis and visible light photoredoxcatalysis performed in flow allowed access to a wide range of functionalized N-aryl-substituted tetrahydroisoquinolines (THIQs) in a formal C–H oxidation/Mannichreaction. Strecker type functionalization and copper-catalyzed alkynylation of several N-aryl-substituted THIQs were also successfully performed in flow, giving valuable products with
An efficient methodology for the functionalization of sp3 C–H bond adjacent to nitrogen has been developed utilizing visible light-induced photoredox catalysis. Through optimization of solvent and light source, the reaction can be rapidly achieved to provide the desired product under mild reaction conditions.
