Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and antiviral agents. Its rigid bicyclic structure and defined stereochemistry make it valuable for designing enzyme inhibitors with high selectivity and potency. Commonly employed in medicinal chemistry to construct stereochemically complex molecules, especially in the optimization of drug candidates targeting hepatitis C virus (HCV) and other viral diseases. The amine functionality allows for easy derivatization, enabling rapid exploration of structure-activity relationships in drug discovery programs.
