Enantioselective Organocatalytic C−H Bond Functionalization via Tandem 1,5-Hydride Transfer/Ring Closure: Asymmetric Synthesis of Tetrahydroquinolines

The first organocatalytic enantioselective intramolecular 1,5-hydride transfer/ring closure reaction is described. This redox neutral reaction cascade allows for the efficient formation of ring-fused tetrahydroquinolines in high enantioselectivities.
