A new series of pyrano[4,3-b]chromene and benzopyrano[3,2-c]chromene derivatives have been synthesized via microwave-assisted one-pot, three-component reaction of N-allyl quinolones, cyclic β-diketones, and 4-hydroxy-6-methyl-2H-pyran-2-one/4-hydroxy coumarin in the presence of catalytic amount of ceric ammonium nitrate under solvent-free condition. The(More)
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(More)
Some new 1H-benzo[b]xanthene and 4H-benzo[g]chromene derivatives of N-allyl quinolone were efficiently synthesized via microwave-induced one-pot three component reaction of N-allyl quinolones, 2-hydroxy-1,4-naphthoquinone and cyclic β-diketones/malononitrile, and iso-propylcyanoacetate in the presence of catalytic amount of ceric ammonium nitrate under(More)
A library comprises diversely substituted novel 3,4′-bicarbostyril derivatives have been designed by molecular hybridization technique and synthesized via multi-component reaction . Compounds G22 (MIC = 12.5 µg/mL) and G38 (MIC = 25 µg/mL) exhibited 99% inhibition against Mycobacterium tuberculosis, while compounds G40 (IC50 = 0.019 µg/mL) and G20 (IC50 =(More)
