  Convenient enantioselective synthesis of β-trifluoromethyl-β-aminoketones by organocatalytic asymmetric Mannich reaction of aryl trifluoromethyl ketimines with acetone

  摘要：

  The L-proline-catalyzed asymmetric Mannich reaction has been performed between aryl trifluoromethyl ketimines and acetone to provide, for the first time, chiral beta-aryl-beta-trifluoromethyl-beta-aminoketones in high yields and with 74-92% enantiomeric excesses.
