Several new pyrrolidinopyrazolidinedione, pyrrolidino-Δ2-pyrazolinedione and pyrrolopyrazoledione derivatives were synthesised via the reaction of different arylhydrazones with N-arylmaleimides. The structures of the synthesized heterocyclic derivatives were established on the basis of elemental analyses and spectroscopic data studies.
