Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective synthesis of pharmaceuticals and fine chemicals. Its structure enables high stereocontrol in metal-catalyzed reactions such as allylic substitutions and cyclopropanations. Commonly employed with palladium or copper complexes to achieve high enantiomeric excess. Valued for its stability under reaction conditions and ability to direct the formation of specific stereoisomers in complex organic transformations.
