Abstract: | 6-Formyl-5-methoxy-2-methyl chromone derivatives condensed with 2-thiox-4-imidazolinone derivatives to form the corresponding “10-methoxy-7-methyl-3-thioxochromono [6,7-b]pyrrolo[1,2-a-]-imidazolin-1-one derivatives(IIIa-f) or the 5-arylidene-2-thioxo-4-imidazolinone derivatives(IVa-f). The activity of the NH in the imidazol moiety of(IIIa) was confirmed by formation of the Mannich bases(Va, b). Moreover, alkylation of(IIIa) was undertaken to give the alkylmercapto derivatives(VIa, b). The antimicrobial activities of compoundsIIIb-e, IVa, IVd andIVe were studied. |
