Used as a chiral organocatalyst in asymmetric synthesis, particularly in enantioselective reactions such as Friedel-Crafts alkylations, Michael additions, and Pictet-Spengler reactions. Its rigid bicyclic structure and well-defined stereochemistry make it effective for inducing high enantioselectivity in the formation of carbon-carbon and carbon-heteroatom bonds. Commonly employed in pharmaceutical research for the synthesis of optically active compounds, including intermediates in drug development. The tetrafluoroborate salt enhances stability and solubility in polar organic solvents, facilitating its use in homogeneous catalytic systems.
