Abstract

Several pyrrole derivates with multiple aryl substituents were prepared conveniently in a one pot-reaction from but-2-ene-1, 4-diones and but-2-yne-1, 4-diones via hydrogenation of the carbon–carbon double bond/triple bond followed by amination–cyclization. The reaction could be performed with ammonium formate or alkyl/arylammonium formates under Pd/C in polyethylene glycol-200 (PEG-200) under microwave irradiation. Using this procedure, ...
