Asymmetric desymmetrization of meso-pyrrolidine derivatives was first effected by enantioselective oxidation of the CH bond α to the nitrogen atom using Mn-salen complex 1b as a catalyst.

for single electron reduction to generate α-amino radicals. Leveraging the ability to generate α-amino radicals from these hemiaminals, we describe a two-step, one-pot, deoxy-arylation of amides utilizing iridium-catalyzed hydrosilylation and photoredox catalysis. This transformation can be tailored toward the late-stage functionalization of biologically relevant molecules, with drug discovery applications
