Oxidative three-component reactions for the direct synthesis of α-amino amides and imides from tertiary amines have been developed. These reactions involve the functionalization of C(sp3)–H bonds adjacent to nitrogen atoms via mild aerobicoxidationusingvisiblelightphotoredoxcatalysis. The protocols are applicable to a wide range of amines and isocyanides, as well as water and carboxylic acids

A continuous flow procedure for the efficient metal-free, visible light photoredox-catalyzed alpha-functionalization of tertiary amines has been developed. Rose Bengal has been identified as an effective organic photocatalyst for continuous flow C-C and C-P bond formations as well as multicomponent reactions.
