Widely used as a chiral ligand in asymmetric catalysis, this compound plays a key role in enantioselective transformations such as hydrogenation and cross-coupling reactions. Its steric bulk and well-defined chiral environment enable high enantioselectivity in the synthesis of complex organic molecules, including pharmaceuticals and natural products. It is particularly effective in ruthenium- or rhodium-catalyzed asymmetric hydrogenations, where it helps generate chiral centers with high optical purity. Due to its modular structure, it is also employed in the development of new catalytic systems for stereoselective C–C and C–heteroatom bond formations.
