Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations. Its rigid adamantane-containing structure provides steric bulk and stability, enhancing stereochemical control in reactions such as asymmetric aldol, Diels-Alder, and Michael additions. Commonly coordinates with transition metals like copper or nickel to form efficient catalytic systems for producing enantiomerically enriched compounds, valuable in pharmaceutical and fine chemical synthesis.
