Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and antiviral agents. Its structure supports the formation of complex heterocyclic systems found in bioactive molecules. Commonly employed in medicinal chemistry for constructing chiral building blocks due to its stereochemical stability and functional group compatibility. Also utilized in solid-phase and solution-phase peptide synthesis where protection of amine and carboxylic acid functionalities is required. Its Boc-protected amine allows for controlled deprotection and coupling steps in multi-step syntheses.
