A series of chiral phosphite‐type ligands was tested in asymmetric Ir‐catalyzed hydrogenation of quinolines and 2,4,5,6‐tetrahydro‐1H‐pyrazino(3,2,1‐ j , k )carbazole. Hydrogenation of quinaldine hydrochloride provided superior enantioselectivity up to 65% ee compared to quinaldine free base. The ligands were tested for the first time in the asymmetric Ir‐Ircatalyzed hydrogenation of 2,4,5,6‐tetrahydro‐1H‐pyrazino(3,2,1‐ j , k )carbazole yielding the antidepressant drug, pirlindole.
