The term “privileged ligands” was coined many years ago to describesystems that create effective asymmetric environments formechanistically unrelated reactions (1). In terms of asymmetrichydrogenation electron rich P-chiral ligands (Figure 1) have beendemonstrated to be privileged in this field. Rhodium catalysts based onthese ligands have been shown to have high activity and selectivity fora broad range of asymmetric hydrogenation reactions. ...
