Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations. Its rigid, well-defined stereochemistry makes it effective in coordinating with metal centers such as copper or nickel, enabling high enantioselectivity in reactions like cyclopropanations, aldol additions, and Diels-Alder reactions. Due to the bulky tert-butyl and aryl groups, it provides significant steric control, enhancing selectivity. Commonly employed in academic and industrial research for developing chiral pharmaceuticals and fine chemicals where stereochemical purity is critical.
