Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective transfer hydrogenation reactions. It plays a key role in the reduction of ketones and imines, enabling high enantioselectivity in the synthesis of chiral alcohols and amines, which are important intermediates in pharmaceuticals and fine chemicals. Its rigid imidazolidine backbone and multiple stereocenters enhance stereocontrol during catalytic processes. Often employed with ruthenium or iridium complexes to achieve efficient catalytic performance under mild conditions.
