  Highly Chemoselective Formation of Aldehyde Enamines under Very Mild Reaction Conditions

  摘要：

  Although ketone enamines are widely used in organic synthesis, aldehyde enamines are rarely employed due to the limitations of their preparation using known methods (need for acid or base, excess of amine, and/or elevated temperature). We have successfully developed rapid and particularly mild condensation conditions (1 h, 0 degrees C, 1.2 equiv of amine) leading to di- and trisubstituted enamines with excellent conversion (84-100%). Remarkably high chemoselectivity was observed with complete discrimination between aldehyde and ketone, among other functional groups positively tested.
