摘要：
An efficient and straightforward procedure has been developed for synthesis of mono and bis-N-aryl/alkyl-3-aminodihydropyrrol-2-one-4-carboxylates via one-pot four-component domino reaction of amines, dialkyl acetylenedicarboxylates, and formaldehyde, in the presence of p-TsOH center dot H2O (15 mol%), in MeOH at ambient temperature. The salient advantages of this method are mild reaction conditions, high to excellent yields, shorter reaction times, atom economy, easy operation, and no column chromatographic separation.
