Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of enantiomerically pure drugs. Its structure serves as a key intermediate in creating beta-amino acids and peptidomimetics, which are important in drug design for improved metabolic stability and bioavailability. Commonly employed in asymmetric synthesis due to its ability to direct stereoselective transformations. Also utilized in the preparation of catalysts and ligands for enantioselective reactions.
