Used as a chiral catalyst ligand in asymmetric synthesis, particularly in enantioselective transformations such as hydrogenation and cross-coupling reactions. Its sterically hindered structure and electron-donating properties enhance selectivity and reactivity with transition metals like palladium, rhodium, and iridium. Commonly applied in pharmaceutical and fine chemical manufacturing where high enantiomeric purity is required. The compound’s rigid backbone supports stable metal coordination, improving catalytic efficiency and turnover in demanding reaction conditions.
