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 asymmetric synthesis of tetrahydroquinolines has been achieved via oxidation and 1,5‐hydride transfer/ring‐closure cascade. The feature of this research is one‐pot transformation of 3‐arylprop‐2‐en‐1‐ol derivatives into tetrahydroquinolines using o‐iodoxybenzoic acid‐mediated oxidation and internal redox reactions. The synthetically useful ring‐fused tetrahydroquinoline derivatives
