Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective transformations such as hydrogenation and transfer hydrogenation reactions. Its stereochemistry enables high enantioselectivity when coordinating with transition metals like ruthenium or rhodium. Commonly applied in the synthesis of chiral amines and alcohols, which are key intermediates in pharmaceuticals and fine chemicals. Also employed in organocatalytic processes where precise stereocontrol is required. Its bulky sec-butyl and p-tolyl groups enhance steric differentiation, improving enantioselectivity in various bond-forming reactions.
