Catalytic Asymmetric Synthesis of Trifluoromethylated γ-Amino Acids via Umpolung Addition of Trifluoromethyl Imines to Carboxylic Acid Derivatives
Enabled by the discovery of novel cinchona alkaloid-derived chiral phase-transfer catalysts, highly chemo-, regio-, diastereo- and enantioselective umpolung additions of trifluoromethyl imines to α, β-unsaturated N-acylpyrroles were realized. With a catalyst loading ranging from 0.2 to 5.0 mol%, thi...
