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 catalysts, especially with rhodium and ruthenium complexes. Commonly applied in the synthesis of pharmaceutical intermediates and fine chemicals where precise stereocontrol is required. Also employed in academic research to develop new catalytic asymmetric transformations.
