| Abstract: | Several new pyrrolopyrazoles were synthesised via the reaction of thiazolonylarylhydrazones with N-arylmaleimides followed by partial dehydrogenation using bromobenzene and complete aromatization using nitrobenzene. Structures were elucidated by elemental analyses and spectral data studies. |
