A CuH-catalyzed atropoenantioselective reduction of Bringmann's lactones via dynamic kinetic resolution has been disclosed. This protocol features 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.
