Used in asymmetric synthesis as a chiral catalyst or chiral auxiliary, particularly in enantioselective reactions such as the alkylation of carbonyl compounds. It is also employed in the resolution of racemic mixtures due to its ability to form diastereomeric salts with chiral acids. Additionally, it serves as a ligand in metal-catalyzed asymmetric transformations. Its natural origin and structural features make it valuable in pharmaceutical research for developing enantiomerically pure drugs.
