Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other biologically active molecules. Its rigid azabicyclic structure helps in conformational restriction, enhancing selectivity and potency in drug candidates. Commonly employed in medicinal chemistry for constructing complex heterocyclic systems, especially in the design of enzyme inhibitors targeting viral or metabolic diseases. The Boc-protected amine and carboxylic acid functionalities allow for straightforward coupling and deprotection steps in multi-step organic syntheses.
