Abstract

Two novel chiral Br?nsted acids 3b and 3c were prepared without involving the complexity of Suzuki coupling. Catalyst 3c bearing two additional hydroxyl groups at 3 and 3′ positions of axially chiral 1,1-binaphthalene-2,2′-diol phosphoric acid was applied in a model Mannich reaction to afford β-amino ester in high yield (92%) and enantiomeric excess (91%) at low reacting temperature of −40°C. In addition, those β-amino ester derivatives with high yields and excellent enatioselectivities were obtained in the presence of catalyst 3c under the above condition.
