The aim of this present study was to synthesize 2-substituted and 1,2-disubstituted benzimidazole derivatives to investigate their antibacterial diversity for possible future drug design. The structure-based design of precursors 2-(1H-benzimidazol-2-yl)aniline 1, 2-(3,5-dinitro phenyl)-1H-benzimidazole 3 and 2-benzyl-1H-benzimidazole 5 were achieved by the condensation reaction of o-phenylenedi...

Purpose: The article is aimed to synthesize,characterize and screening the biological activity of a series of Synthesis of 1-(2-(3-(3-chloro-1-(4-substituted phenyl)-4-tetrazole-2-yl)-1H-indol-1-yl)acetyl)-4-(2-(4substituted phenyl)hydrazono)-3-(trifluoromethyl)-1H-pyrazol-5(4H)-one 4(a-f). Indole-3-carbaldehyde and chloro ethyl acetate were dissolved in DMF. To this reaction mixture anhydrous ...

The complexes containing mixed of ligands [5-(3-chlorophenyl) -1,3,4-oxadiazole-2-thione(CPoxSH)] and diphosphines Ph2P(CH2)nPPh2 (diphos)(n=1-4), are prepared by the reaction [Hg(CPoxS)2] or [M(H2O)2(CPoxS)2] (M = Co, Ni ) with one mole proportion diphosphine gave tetrahedral type [Hg(CPoxS)2(diphos)]. While an octahedral cobalt(II) nickel(II) ions [M(H2O)(CPoxS)2(diphos)] when Co receptivity....

Here we describe a full structural elucidation of the diethyl (2-(4-phenyl-1H-1,2,3-triazol-1-yl)benzyl) phosphate. This compound is common by-product present in synthetic protocols to access α-hydroxy phosphonate compounds through Phospha-Brook rearrangement. Thus, complete NMR characterization this rearrangement was performed by 1H, 13C{1H}, 31P{1H}, COSY, HSQC, and HMBC experiments. Addition...

We have isolated the stable as well as the metastable tautomers of 1-deazapurine in the solid state by exploiting principles of supramolecular selectivity in the context of cocrystal design.
