Used in pharmaceutical synthesis, particularly in the development of protease inhibitors and other bioactive molecules. Its hydroxyl and protected amine functionalities allow selective chemical modifications, making it a valuable building block in medicinal chemistry. The Boc-protected amine ensures stability during reactions, while the hydroxy group can be further derivatized for linker attachment or scaffold diversification. Commonly employed in the synthesis of enzyme inhibitors where the azabicyclic core contributes to conformational rigidity and target binding selectivity.
