Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations such as hydrogenation and cyclopropanation reactions. Its rigid indene backbone and oxazoline rings provide a well-defined chiral environment, enhancing stereoselectivity. Commonly coordinates with transition metals like rhodium or copper to form catalysts that deliver high enantiomeric excess in the synthesis of pharmaceutical intermediates and fine chemicals. Valued for its stability under reaction conditions and ability to be tailored for specific substrate classes.
