Widely used as a chiral bidentate ligand in asymmetric catalysis, enabling high enantioselectivity in hydrogenation and cross-coupling reactions. Its rigid backbone and stereochemistry make it ideal for inducing chirality in transition metal complexes, particularly with rhodium and ruthenium, enhancing the efficiency of producing enantiomerically pure pharmaceuticals and fine chemicals. Commonly employed in the synthesis of bioactive molecules where stereocontrol is critical.
