Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as hydrogenation, cross-coupling, and C–H activation. Its rigid, sterically hindered structure enhances enantioselectivity, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. Effective in palladium- and rhodium-based catalytic systems where high stereocontrol is required. Also employed in the development of novel catalysts for industrial-scale enantioselective transformations.
