This compound is a chiral phosphoric acid catalyst derived from BINOL, bearing electron-withdrawing trifluoromethyl groups at the 3,3′-positions. It is widely used in asymmetric organic synthesis, including Friedel–Crafts reactions, Diels–Alder cycloadditions, and imine reductions. The strong acidity and chiral cavity enable high enantioselectivity (often >90% ee) in C–C and C–N bond formations. It serves as a key catalyst for synthesizing chiral pharmaceuticals, agrochemicals, and natural products. In academic research, it is a benchmark catalyst for developing new asymmetric methodologies. Due to its stability and high activity, it is favored in both laboratory and industrial pilot-scale synthesis.
