Graphical Abstract
In buffered water, a broad range of quinoline derivatives underwent asymmetric transfer hydrogenation in air with the rhodium catalyst 1 and sodium formate as the hydrogen source to furnish synthetically important 1,2,3,4-tetrahydroquinolines with excellent enantioselectivities (see scheme; R=H, Me, F, Cl, Br, OMe; R′=alkyl, aryl).
