Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations. Its rigid indene backbone and oxazoline rings provide excellent stereocontrol, making it effective in reactions such as asymmetric alkylations, cyclopropanations, and Diels-Alder reactions. Commonly coordinates with metals like copper, nickel, or palladium to form catalysts that deliver high enantioselectivity in the synthesis of pharmaceuticals and fine chemicals. Valued for its stability under reaction conditions and ability to induce high chiral induction.
