Atropo-Enantioselective Oxidation-Enabled Iridium(III)-Catalyzed C?H Arylations with Aryl Boronic Esters

Atropo-enantioselective biaryl coupling through C?H bond functionalization is an emerging technology allowing direct construction of axially chiral molecules. This approach is largely limited to electrophilic coupling partners. We report a highly atropo-enantioselective C?H arylation of tetralone derivatives paired with aryl boronic esters as nucleophilic components. The transformation is catalyzed by chiral cyclopentadienyl (Cpx) iridium(III) complexes and enabled by oxidatively enhanced reductive elimination from high-valent cyclometalated Ir-species.
