A series of C3*-TunePhos chiral diphosphine ligands has been successfully applied in the iridium-catalyzed enantioselective hydrogenation of quinolines, and this methodology provided an efficient access to a variety of optically active tetrahydroquinolines with up to 93% ee. Furthermore, attempts on the asymmetric hydrogenation of quinoline N-oxide are also discussed.
