Used as a chiral ligand in asymmetric synthesis, particularly in catalytic reactions such as the addition of diethylzinc to aldehydes, enabling the production of enantiomerically pure alcohols. It is also employed in the preparation of chiral catalysts for organic transformations, including hydrogenation and carbon-carbon bond formation. Additionally, it serves as a building block in the synthesis of chiral polymers and materials with potential applications in optoelectronics and chiral recognition. Its role in enantioselective reactions makes it valuable in pharmaceutical and fine chemical industries for producing optically active compounds.
