Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of antiviral and antidiabetic drugs. Its stereochemistry and functional groups allow for selective reactions, making it valuable in constructing complex molecules with high enantiomeric purity. Commonly employed in medicinal chemistry for structure-activity relationship studies and optimization of drug candidates. The Boc-protected amine and hydroxyl group enable stepwise derivatization, facilitating peptide-like coupling and heterocycle formation in advanced synthetic routes.
