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 constructing stereoselective drug molecules. The tert-butyl carbamate-protected amine and the trifluoroacetamido group allow for selective deprotection and further functionalization, enabling efficient multi-step synthesis. Commonly employed in medicinal chemistry for optimizing potency and metabolic stability in drug candidates.
