general, high-yielding amine Cα–H cyanation protocol via photoredox catalysis. Inexpensive NaCN is employed as the cyanidesource and air is the external oxidant, resulting in mild and highly functional group tolerant conditions. Notably, efficient Cα–H cyanations of secondary and tertiary aliphatic amines and of complex, biologically active compounds (drugs) can be performed using the established methodology
Facilitating drug discovery: We describe a novel method for the selective catalytic N-dealkylation of drugmolecules on a nanoporousgold (NPG) catalyst producing valuable N-dealkylated metabolites and intermediates. Various examples examined in this study showed that aerobic catalytic N-dealkylation of drugmolecules on NPG has a broad scope, supporting N-deethylation, N-deisopropylation and N-demethylation

N-dealkylation of tertiaryamines via photoredox catalysis and its application in late-stage functionalization. Using the developed method, more than 30 diverse aliphatic, aniline-type, and complex substrates are shown to undergo N-dealkylation, providing a method with broader functional group tolerance compared to methods found in the literature. The scope also includes tertiary and secondary amine molecules
