β-Enaminones and β-enamino esters,which combine the nucleophilic enamine and the electrophilic enone(ester)moieties into one molecule,represent important synthetic building blocks and have been extensively employed as synthons for the synthesis of a wide variety of heterocycles.3-Arylamino-1-methyl-1H-pyrrole-2,5-diones,which can be easily prepared from the reaction of arylamine,dimethyl acetylenedicarboxylate and methylamine,maintain the structural character of β-enaminones and β-enamino esters.
