Used as a chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and other biologically active molecules. Its structure supports peptide mimicry, making it valuable in medicinal chemistry for designing drugs with enhanced metabolic stability and target selectivity. Commonly employed in asymmetric synthesis to introduce stereochemical control during the preparation of complex organic molecules. Also utilized in the production of enzyme inhibitors where aromatic and steric features are critical for activity.
