Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and antiviral drugs. Its stereochemistry allows for selective interactions in biological systems, making it valuable in creating enantiomerically pure compounds. Commonly employed in medicinal chemistry for constructing complex nitrogen-containing heterocycles. Also utilized in the preparation of drug candidates targeting metabolic and neurological disorders due to its ability to mimic peptide structures and enhance bioavailability.
