Enantioselective transfer hydrogenation of benzofuranyl arylketones proceeds with moderate to good enantioselectivity even when the aryl group is not sterically differentiated by ortho-substituents. The best results are obtained with substrates that are functionalised by electron-withdrawing aryl groups that contrast with the electron-rich benzofuran, which is consistent with [Ru― ArC―H]·Ar π interactions
