A one-pot synthesis of 3-alkyl-2-phenyl-1-vinylpyrroles, giving high yields at atmospheric pressure, was developed on the basis of reacting alkyl phenyl ketoximes with acetylene in a KOH-DMSO system (the Trofimov reaction).

Conditions were found for the synthesis of 3-alkyl-2-arylpyrroles using the Trofimov reaction at 50-70 deg C both at elevated and atmospheric pressure.O-Vinyloximes and 3H-5-hydroxy-4,5-dihydropyrroles were isolated as intermediates.

New representatives of the 2-arylpyrrole series were obtained with yields of 36-90percent from the oximes of alkyl aryl ketones by the Trofimov reaction.When vinyl chloride was used instead of acetylene under the same conditions (potassium hydroxide-DMSO, 80-100 deg C), the pyrroles were obtained with yields of 2-7percent.
