A robust and efficient nickel–phosphine complex has been discovered for the asymmetric hydrogenation of aliphatic ketoacids. A proton promoted the activation of C=O bonds and controlled the stereoselectivity through hydrogen bonds to obtain the corresponding products in high yields with excellent enantioselectivities.
