Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations such as hydrogenation and transfer hydrogenation reactions. Its stereochemically defined structure enables high enantioselectivity when coordinating to metal centers like ruthenium, rhodium, or iridium. Commonly applied in the synthesis of chiral alcohols and amines, which are key intermediates in pharmaceuticals and fine chemicals. The bulky tert-butyl and sec-butyl groups enhance steric control around the metal center, improving selectivity and reaction efficiency. Also employed in academic research to develop new catalytic systems for asymmetric synthesis.
