Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and antiviral agents. Its rigid bicyclic structure and functional handles make it valuable for constructing stereochemically defined nitrogen-containing compounds. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing drug candidates targeting enzymes where spatial orientation of functional groups is critical. The Boc-protected amine allows for controlled deprotection and coupling in peptide-like frameworks, enabling efficient library synthesis in drug discovery.
