Preparation of Trifluoromethylsulfonylpyrroles via Mesoionic Intermediates

Abstract

Abstract The reaction of N-substituted-N-formylglycine and phenyltrifluoromethylsulfonylacetylene in acetic anhydride results in the formation of substituted-4-trifluoromethylsulfonylpyrroles. In our continuing efforts1 to prepare novel hetero structures via mesoionic intermediates, we would like to report the general preparation of
