Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other biologically active molecules. Its protected amine and ester functional groups allow for selective reactions in multi-step organic syntheses. Commonly employed in medicinal chemistry for constructing peptidomimetics and drug candidates targeting viral infections and metabolic disorders. The Boc-protected amine ensures stability during reactions, while the ester can be hydrolyzed or further modified to extend molecular structure.
