Widely used as a chiral ligand in asymmetric catalysis, enabling the synthesis of enantiomerically pure compounds. It is particularly effective in transition metal-catalyzed reactions such as asymmetric hydrogenation and transfer hydrogenation, where it helps produce pharmaceutical intermediates with high optical purity. Its rigid chiral structure enhances stereoselectivity, making it valuable in the development of chiral amines, amino acids, and other bioactive molecules. Also employed in the preparation of chiral catalysts like Ru(II) or Rh(III) complexes for industrial and academic research applications.
