Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective transformations such as hydrogenation and carbon-carbon bond-forming reactions. Its rigid indene backbone and chiral oxazoline rings enhance stereocontrol, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. Effective with transition metals like rhodium and iridium, it helps achieve high enantiomeric excess in catalytic processes.
