Abstract

Herein we reported a facile approach to synthesize pyrrole derivatives under mild conditions. The reaction proceeds cycloaddition reactions between (E)-1-aryl-3-(2-(arylethynyl)phenyl)prop-2-en-1-one and commercially available p-toluenesulfonylmethyl isocyanide. Although the triple bond in the substrate was not involved in the reaction process, this work still provided a method for the synthesis of pyrrole derivatives.
