Widely used as a chiral ligand in asymmetric catalysis, this compound plays a key role in enantioselective transformations. It forms complexes with transition metals like rhodium, iridium, and copper, which are essential in hydrogenation, cyclopropanation, and conjugate addition reactions. Due to its rigid aromatic backbone and well-defined chiral environment, it helps achieve high enantiomeric excess in the synthesis of pharmaceuticals and fine chemicals. Its steric bulk from the tert-butyl groups enhances selectivity by controlling the approach of substrates to the metal center. Commonly employed in academic and industrial research for developing efficient catalytic processes.
