, p. 16648 - 16651 (2015)
A chiral Bronsted acid catalyzed dehydrogenative kinetic resolution of tetrahydroquinoline derivatives, which are representative of cyclic secondary amines, based on their hydrogen transfer to aromatic imines was efficiently achieved with high enantioselectivities. This hydrogen transfer of tetrahydroquinolines to imines was not driven by their aromatization to quinolines. This dehydrogenative kinetic resolution could be also applied to the asymmetric synthesis of various benzofused heterocycles containing secondary amine cores.

The first highly enantioselective hydrogenation of 2-arylquinolinium salts by using cationic dinuclear iridium (III) halide complexes with difluorphos and some atropisomeric chiral diphosphine ligands as catalyst precursors has been reported. Asymmetric h
