Abstract

Abstract: Reaction of a-trifluoromethyl, a-cyano, and a-ethoxycarbonyl alkenyl sulfones with ethyl isocyanoacetate in the presence of a base gave 4-substituted pyrrole-2-carboxylates in moderate to good yields. Key words: pyrrole-2-carboxylate, trifluoromethyl, BartonœZard reaction, alkenyl sulfones
