Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as asymmetric hydrogenation and cross-coupling. Its rigid, well-defined stereochemistry enhances enantioselectivity, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. Effective in rhodium- and ruthenium-based catalytic systems, it helps achieve high ee (enantiomeric excess) in the production of chiral intermediates. Also employed in academic research to develop new asymmetric transformations.
