This compound is primarily utilized in asymmetric synthesis and chiral catalysis, where it serves as a key intermediate or ligand in the production of enantiomerically pure compounds. Its structure, featuring two tosyl groups and phenyl rings, makes it effective in facilitating stereoselective reactions, particularly in the synthesis of pharmaceuticals and fine chemicals. It is often employed in the development of chiral catalysts for transformations such as hydrogenation, epoxidation, and other enantioselective processes. Additionally, its rigid and well-defined chiral framework is valuable in the study of stereochemical outcomes in organic reactions, aiding in the design of novel catalytic systems.
