Enantioselective organocatalytic oxidative enamine catalysis–1,5-hydride transfer–cyclization sequences: asymmetric synthesis of tetrahydroquinolines†
Abstract
The first organocatalytic enantioselective intramolecular oxidative enamine catalysis and 1,5-hydride transfer–ring closure reaction cascade is described. This neutral reaction cascade allows for the efficient formation of ring-fused tetrahydroquinolines with high enantioselectivities.
