Chiral cyclopropenimine-catalyzed enantioselective Michael additions between benzophenone-imine of glycine esters and α,β-unsaturated pyrazolamides

A highly chiral cyclopropenimine-catalyzed enantioselective Michael addition between benzophenone-imine of glycine esters and β-substituted α,β-unsaturated pyrazolamides has been realized to afford Michael adducts in up to 95% yield and 99% ee.
