Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and other biologically active molecules. Its stereochemistry allows for selective interactions in asymmetric synthesis, making it valuable in the production of enantiomerically pure drugs. Commonly employed in the preparation of advanced intermediates for medicinal chemistry research, especially in the discovery of antiviral and central nervous system therapeutics. The Boc-protected amine and carboxylic acid functionality enable stepwise coupling and deprotection strategies in multi-step organic syntheses.
