An enantioconvergent method for the alkylation of o-disubstituted aryl ketones with racemic secondaryalcohols is described. This process is mediated by a commercially available iridium catalyst and proceeds via hydrogen borrowing catalysis. The highly enantioenriched β-substituted ketone products were readily cleaved to a wide range of functional groups via retro-Friedel-Crafts acylation.
