A practical and efficient method for the synthesis of 2-aroxy(alkoxy)quinolines has been developed by direct cross-dehydrogenative coupling reaction between quinoline N-oxides and readily available phenols and alcohols in the presence of H-phosphonate and

A new series containing pyrido[1,2-a]benzimidazole derivatives of β-aryloxyquinoline has been synthesized via base catalyzed microwave-assisted multi-component cyclocondensation reaction. This methodology allowed us to achieve the desired products in good yields in very short time with the use of 10 mol% NaOH as a non-hazardous organic base. The chemical structures of compounds 6a-x were elucidated by 1H NMR, 13C NMR, FT-IR, elemental analysis, and mass spectral data. The titled derivatives were tested against a panel of pathogenic strains of bacteria and fungi for antimicrobial activity and against Mycobacterium tuberculosis H37Rv for their antitubercular activity. The structural activity relationship study revealed that antimicrobial and antitubercular potency of the title compounds depends not only on the bicyclic heteroaromatic pharmacophore appended through ether linked aryl ring but also on the nature of the peripheral substituents and may also upon their spatial relationship and positional changes.
