Used as a chiral bidentate phosphine ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as hydrogenation, allylic alkylation, and cross-coupling transformations. Its stereochemistry enhances enantioselectivity, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. The electron-rich dimethylamino groups stabilize metal complexes and improve catalytic efficiency. Commonly employed with rhodium, ruthenium, or palladium complexes for high enantiomeric excess in asymmetric synthesis.
