A highly efficient gold-catalyzed tandem hydroamination/asymmetric transfer hydrogenation provides tetrahydroquinolines in excellent yields and enantioselectivities in the presence of a chiral phosphate. In this reaction, the gold catalyst acts as a π-Lewis acid in the hydroamination step and as an effective chiral Lewis acid in the asymmetric hydrogen-transfer.
