Synthesis and Application of a New Cyclic Phosphoric Acid in Enantioselective Three-Component Mannich Reactions

A novel point-chiral six-membered cyclic phosphoric acid was synthesized starting from an enantiopure precursor via a concise three-step route. Its catalytic performance was evaluated in enantioselective three-component Mannich reactions. Under optimized conditions, the catalyst provided good yields...

description A novel point-chiral six-membered cyclic phosphoric acid was synthesized starting from an enantiopure precursor via a concise three-step route. Its catalytic performance was evaluated in enantioselective three-component Mannich reactions. Under optimized conditions, the catalyst provided good yields and satisfactory enantiomeric excesses (up to 89%). The basic mechanism of the catalysis was also studied by the DFT method.
