Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of antimalarial drugs like chloroquine and analogs. Its rigid bicyclic structure and stereochemistry make it valuable in asymmetric synthesis and the development of bioactive molecules. Also employed in the preparation of catalysts for enantioselective reactions. Commonly utilized in research for designing enzyme inhibitors and receptor ligands due to its ability to mimic natural amino groups in constrained geometries.
