simple ether-directed iridium-catalyzed site- and enantioselective C(sp2)-H borylation of benzhydryl ethers for the first time. Various chiral benzhydryl ethers were obtained with high enantioselectivities in the presence of a tailor-made chiral bidentate boryl ligand. We found that the kineticresolution relay significantly amplified the enantioselectivity. The synthetic utility of the current method was
