Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations such as aldol reactions, Diels-Alder reactions, and allylic alkylations. Its sterically hindered, axially chiral structure enables high enantioselectivity when coordinated with metals like titanium, aluminum, or boron. Commonly employed in the synthesis of pharmaceuticals and fine chemicals where control of stereochemistry is critical. Also utilized in the development of chiral sensors and asymmetric photocatalysis due to its stable helical conformation and ability to induce chirality in reaction environments.
