The title quinoline derivative, 5-chloro-8-{[1-(2-chlorobenzyl)-1H-1,2,3-triazol-4-yl]methoxy}quinoline, was synthesized in a common three-step procedure from 5-chloro-8-hydroxyquinoline using O-propargylation reaction/copper-catalyzed 1,3-dipolar cycloaddition sequence. The structure of the compound was fully characterized by FT-IR, 1H- and 13C-NMR, GC-MS, and elemental analysis. Its physicochemical parameters (Lipinski’s descriptors) were also calculated using the Molinspiration Cheminformatics software. The hybrid obtained could be an interesting model for antifungal bio-essays or a suitable precursor in the synthesis of more complex triazolyl-quinoline hybrids, potential pharmacological agents.

Three new 1,3,4,5-tetrahydro-2H-1,5-benzodiazepin-2-one oximes were synthesized and characterized by the methods of 1H- and 13C-NMR, IR and elemental analysis. Along with previously described compounds bearing one additional methyl group on the 5th nitrogen atom, the new compounds were characterized in bulk by UV?Vis and fluorescence spectroscopy in various solvents. The influence of the nature of the organic solvent on the spectra of the title compounds was investigated and is discussed.

In present work, we have reported the synthesis and characterisation of novel hexahydrospiro[indoline-3,3′-pyrrolizine]-2-one derivatives in good to excellent yields via [3+2] cycloaddtion reaction in regioselective manner. These compounds were synthesized via multicomponent reaction of substituted 3-cinnamoyl-4-hydroxy-6-methyl-2H-pyran-2-one, isatin, L-proline at room temperature. All the synthesized hexahydrospiro molecules were characterized by 1H and 13C NMR, IR spectra, mass spectra and elemental analysis. Regioselectivity in synthesized molecules were also explained on the basis of secondary orbital interactions. A simple and facile methodology is developed which has great importance in synthetic chemistry.

AbstractA new series of twenty four derivatives of pyrano[3,2-c]chromene IVa-x bearing 1H-pyrazole were synthesized by a one pot, base-catalyzed cyclocondensation reaction of 1H-pyrazole-4-carbaldehyde Ia-l, malononitrile II and 4-hydroxycoumarin IIIa-b. All the synthesized compounds were characterized by elemental analysis, FT-IR, 1H NMR and 13C NMR spectral data. All the synthesized compounds were screened against six bacterial pathogens, namely B. subtilis, C. tetani, S. pneumoniae, S. typhi, V. cholerae, E. coli and for antifungal activity against two fungal pathogens, A. fumigatus and C. albicans using the broth microdilution MIC method. Some of the compounds were found to be equipotent or more potent than commercial drugs against most of employed strains, as evident from the screening data.
