A fine selection : The installation of chiral centers at the α position of ketones is achieved with excellent enantioselectivity by means of iridium‐catalyzed asymmetric hydrogenation of α,β‐unsaturated ketones under mild conditions. The catalyst incorporates a phosphinooxazoline (PHOX)‐based ligand, which exhibits high levels of asymmetric induction (see scheme; BAr F − =tetrakis[3,5‐bis(trifluoromethyl)phenyl]borate; cod=cyclooctadiene).
