Used as a chiral organocatalyst in asymmetric synthesis, particularly in enantioselective cyclization and cyclodehydration reactions. It promotes the formation of chiral heterocyclic compounds with high enantioselectivity, which are valuable intermediates in pharmaceutical synthesis. Its rigid bicyclic structure and positive charge enhance its ability to stabilize transition states through non-covalent interactions such as hydrogen bonding and ion pairing. Commonly applied in the synthesis of bioactive molecules where stereochemical control is critical.
