This compound is primarily utilized as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions. Its structure, featuring diphenylphosphine groups and a rigid decahydroquinoxaline backbone, makes it highly effective in inducing enantioselectivity. It is commonly employed in hydrogenation reactions, where it helps produce chiral molecules with high enantiomeric purity, crucial in the synthesis of pharmaceuticals and fine chemicals. Additionally, its stability and selectivity make it suitable for use in cross-coupling reactions, enabling the formation of complex organic compounds with precise stereochemical control.
