via a cascade transfer hydrogenation and dynamic kinetic resolution strategy is described. This protocol features broad substrate scope and good functional group tolerance and allows the rapid assembly of axially chiral biaryls in good to high yields with high to excellent enantioselectivities. In addition, such structural motifs may have potential applications in enantioselective catalysis as chiral
a broad substrate scope and good functional group tolerance and allows the rapid assembly of various valuable axially chiral biaryls in good to high yields (up to 92% yield) with high to excellent enantioselectivities (up to 96% ee). Moreover, this report represents a rare example that a carbonyl group of esters is reduced under homogeneous asymmetric CuH catalysis.

The implementation of lipase catalysis as a tool for the preparation of optically active biaryls is discussed. While attempts toward dynamic kinetic resolution based on the catalytic ring opening of configurationally unstable biaryl lactones were fruitless, kinetic resolution via transesterification of hydroxymethyl-decorated substrates was successfully employed in the generation of optically enriched, axially chiral biaryls.
