Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its structural features, including the bicyclic framework and protected amine group, make it valuable in medicinal chemistry for constructing peptidomimetics and enzyme inhibitors. Commonly employed in solid-phase and solution-phase peptide synthesis due to its stability and stereochemical control. Also utilized in the preparation of drug candidates targeting viral infections and neurological disorders.
