The first organocatalytic enantioselective intramolecular oxidative enamine catalysis and 1,5-hydride transfer-ring closure reactioncascade is described. This neutral reactioncascade allows for the efficient formation of ring-fused tetrahydroquinolines with high enantioselectivities.

organocatalytic synthesis of tetrahydroquinolines has been achieved via an aerobic oxidation and a 1,5-hydridetransfer/cyclization sequence. The feature of this research is a one-pot transformation of 3-arylprop-2-en-1-ol derivatives into tetrahydroquinolines using a Ru(VII)-catalyzed aerobic oxidation and highly efficient internal redox reactions. The synthetically useful ring-fused tetrahydroquinoline derivatives
