  We describe an efficient one-step synthesis of pyrrolo[3,4-c]quinolinedione derivatives using ethylenediamine diacetate (EDDA)-catalyzed cascade reactions of isatins and β-ketoamides. It is the first direct conversion of isatins to pyrrolo[3,4-c]quinolinedione derivatives via C–N bond cleavage and isatin ring expansion. Furthermore, this reaction provides a one-step synthetic route for the production

  我们描述了一种高效的一步合成吡咯并[3,4- c ]喹啉二酮衍生物，使用乙二胺二乙酸酯（EDDA）催化的isatins和β-ketoamides级联反应。这是首次通过C–N键断裂和Isatin环扩环将Isatins直接转化为吡咯并[3,4- c ] quinolinedione衍生物。此外，该反应提供了一步合成路线，用于生产通常使用多步反应制备的生物学上感兴趣的复杂分子。

  Inorganic solid supports are useful media for the rapid and efficient synthesis of a library of quinoline-3,4-dicarboximides. In particular, wet clay K10 was shown to be the best medium for the condensation reaction between 2-methylquinoline-3,4-dicarboxylic anhydride and several primary amines. Microwave irradiation is essential for a rapid and complete conversion.

  Twenty -substituted pyrrolo[3,4-]quinoline-1,3-diones were synthesized by a cyclization reaction of Pfitzinger's quinoline ester precursor with the selected aromatic, heteroaromatic and aliphatic amines. The structures of all derivatives were confirmed by IR, H NMR, C NMR and HRMS spectra, while their purity was determined using HPLC techniques. Almost all compounds were identified as a new class ofpotent

• Microwave-Assisted Synthesis of Diverse Pyrrolo[3,4-<i>c</i>]quinoline-1,3-diones and Their Antibacterial Activities

  With the aim of developing a general and practical method for library production, a novel and efficient two-phase microwave-assisted cascade reaction between isatins and beta-ketoamides in [Bmim]BF4/toluene was developed for the synthesis of pyrrolo[3,4-c]quinoline-1,3-diones. The features of this methodology are, the use of microwave-assisted rapid synthesis, mild reaction conditions, high yields, operational simplicity, facile product separation, and recyclability. Furthermore, the antibacterial activities of the pyrrolo[3,4-c]quinoline-1,3-dione derivatives produced were evaluated against Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, and Enterobacter aerogenes) and Gram-positive bacteria (Bacillus cereus and Staphylococcus aureus). These derivatives showed antibacterial activities against Gram-positive strains that were at least equivalent to that against Gram-negative strains. Compound 73,5} displayed the most potent antibacterial activity against P. aeruginosa (MIC = 0.5 mu g/mL) and greater activity than standard ampicillin (MIC = 1 mu g/mL). Compound 74,7} exhibited the best inhibitory activity against E. coli and E. aerogenes (MIC = 1 and 0.5 mu g/mL), compared with the standard ampicillin (both MICs = 1 mu g/mL). The synthesized pyrrolo[3,4-c]quinoline-1,3-diones are expected to be widely used as lead compounds for the development of new antibacterial agents.
