Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other biologically active molecules. Its protected amine and carboxylic acid functionalities make it valuable in peptide coupling and solid-phase synthesis. Commonly employed in medicinal chemistry for constructing complex heterocyclic systems, especially in drugs targeting viral infections and metabolic disorders. The Boc-protected group allows for selective deprotection and further functionalization, enabling stepwise assembly of multi-step synthetic pathways.
