An asymmetric decarboxylative Csp(3)-Csp(2) cross-coupling has been achieved via the synergistic merger of photoredox and nickel catalysis. This mild, operationally simple protocol transforms a wide variety of naturally abundant α-amino acids and readily available aryl halides into valuable chiral benzylic amines in high enantiomeric excess, thereby producing motifs found in pharmacologically active

1-(4-(9H-Carbazol-9-yl)phenyl)-3-amino-9H-fluorene-2,4-dicarbonitrile as a new photocatalyst for the decarboxylative cross-coupling reaction of alpha-amino acids or alpha-oxy carboxylic acids with arylnitriles is described. This light-driven reaction enables a variety of benzylic amines and ethers to be prepared from readily available starting materials under mild conditions.

The directdecarboxylativearylation of α-amino acids has been achieved via visible light-mediated photoredoxcatalysis. This method offers rapid entry to prevalent benzylic amine architectures from an abundant biomass, specifically α-amino acid precursors. Significant substrate scope is observed with respect to both the amino acid and arene components.
