Widely used as a chiral ligand in asymmetric catalysis, this compound plays a key role in enantioselective transformations. It is particularly effective in copper-catalyzed cyclopropanation and conjugate addition reactions, where it helps achieve high enantiomeric excess. Its rigid binaphthyl backbone and oxazoline rings provide excellent stereocontrol, making it valuable in the synthesis of chiral intermediates for pharmaceuticals and fine chemicals. The ligand is also employed in nickel- and palladium-catalyzed asymmetric reactions, enhancing selectivity in carbon–carbon bond-forming processes. Due to its tunable steric and electronic properties, it supports efficient catalysis under mild conditions, often with low catalyst loading.
