3-ALKYL-2-PHENYL-1-VINYLPYRROLES FROM KETOXIMES AND ACETYLENE: AN IMPROVED SYNTHESIS BY THE TROFIMOV REACTION

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).
