Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring stereoselective control. Its structure supports the formation of complex nitrogen-containing heterocycles, making it valuable in medicinal chemistry for drug discovery. Commonly employed in asymmetric synthesis and catalysis due to its ability to act as a ligand or intermediate in enantioselective reactions. Also utilized in the preparation of protease inhibitors and central nervous system agents.
