Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors. Its functional groups allow for selective reactions in multi-step organic syntheses, making it valuable in creating complex drug molecules. Commonly employed in research settings for modifying bioactive structures, especially in antiviral and oncology-related drug discovery. The presence of protective groups (Boc and TBS) enables controlled deprotection and coupling steps, ensuring high specificity during peptide or peptidomimetic assembly.
