Used as a chiral organocatalyst in asymmetric synthesis, particularly in enantioselective cyclization and fluorination reactions. Its rigid bicyclic structure and perfluoroaryl group enhance stereocontrol and catalyst stability under oxidative conditions. Commonly applied in the synthesis of bioactive molecules where high enantiomeric excess is required. The tetrafluoroborate counterion improves solubility in polar aprotic solvents, facilitating homogeneous reaction conditions. Also explored in photoredox catalysis due to its ability to participate in single-electron transfer processes.
