Used as a chiral intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals where stereochemistry plays a critical role. Its rigid polycyclic structure and trichloromethyl group make it valuable in asymmetric synthesis, helping to control stereoselectivity during carbon–carbon bond formation. Commonly employed in the development of protease inhibitors and antiviral agents due to its ability to mimic peptide transition states. Also utilized in agrochemical research for designing enantioselective catalysts and enzyme inhibitors.
