Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations such as hydrogenation and transfer hydrogenation reactions. Its rigid biimidazole backbone and chiral environment enable high stereoselectivity when coordinating to metal centers like ruthenium, rhodium, or iridium. Commonly employed in the synthesis of chiral amines and alcohols, which are key intermediates in pharmaceuticals and fine chemicals. Also explored in organocatalytic systems due to its ability to form stable hydrogen-bonding networks that influence stereochemical outcomes.
