Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as asymmetric hydrogenation and cross-coupling. Its steric bulk and well-defined chiral environment enable high enantioselectivity in the synthesis of complex organic molecules, including pharmaceuticals and fine chemicals. Commonly employed with rhodium or ruthenium complexes to achieve efficient stereocontrol in the production of chiral amines and other bioactive intermediates.
