Used as a chiral gold-based catalyst in asymmetric synthesis, particularly in enantioselective carbon-carbon bond-forming reactions. It shows high efficiency in promoting transformations such as cycloadditions, hydroarylations, and aldol-type reactions with excellent enantioselectivity. Its bidentate phosphine ligand framework enhances stability and stereochemical control, making it valuable in the synthesis of complex organic molecules, including natural products and pharmaceutical intermediates.
