Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other biologically active molecules. Its structure allows for selective modification in peptide-like frameworks, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in solid-phase and solution-phase peptide synthesis due to the presence of both carboxylic acid and protected amine functionalities. The Boc-protected amine ensures stability during reactions while enabling deprotection for further coupling steps. Frequently utilized in the preparation of drug candidates targeting viral infections and metabolic disorders.
