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 functionalization, making it valuable in medicinal chemistry for building complex cyclic frameworks. The Boc-protected amine and hydroxyl group provide orthogonal reactivity, enabling stepwise coupling and deprotection strategies in multi-step syntheses. Commonly employed in the preparation of drug candidates targeting viral infections and metabolic disorders.
