Abstract
A multicomponent technique was utilized to synthesize pyrroloimidazoles, a novel class of compounds, with exceptional efficiency. The reaction involved the combination of oxoindolinylidene malononitrile, ethyl 2-arylamino-4-dioxo-4-arylbutanoates, hydrazonoyl chlorides, ammonium acetate, and ethyl bromopyruvate in an aqueous solution at room temperature. The presence of Ag/Fe3O4@MWCNTs MNCs intensified the reaction. This study examines the antioxidant properties of pyrroloimidazoles, in addition to other investigations undertaken within the same study. The manufacture of pyrroloimidazole exhibited several advantageous characteristics, such as rapid reactions, elevated yields of the end product, and straightforward separation of the catalyst and product from the reaction mixture.
