Synthesis, reactions and biological activity of some new bis-heterocyclic ring compounds containing sulphur atom
BACKGROUND The derivatives of thieno[2,3-b]thiophene belong to a significant category of heterocyclic compounds, which have shown a wide spectrum of medical and industrial application. RESULTS A new building block with two electrophilic center of thieno[2,3-b]thiophene derivatives 2 has been reported by one-pot reaction of diketone derivative 1 with Br2/AcOH in excellent yield. A variety of h...
متن کاملSynthesis of Some New Heterocyclic Compounds with Potential Biological Activity
A series of new 2-arylimino-3-aryl-5-[5?-(3,4-dichlorophenyl)-2?-furylidene]-4-thiazolidinones (3a-l) have been synthesised by the condensation of 5-(3,4-dichlorophenyl)-2-furaldehyde 1 with 2-arylimino-3-aryl-5H-4-thiazolidinones 2 in glacial acetic acid. The physical and spectral data of the synthesised compounds are determined. The synthesised compounds have been screened for their in vitro ...
متن کاملSynthesis and analysis of some bis-heterocyclic compounds containing sulphur.
A facile and convenient synthesis of a series of bisheterocycles 7a,b 10, 12 and 13a,b containing a thieno[2,3-b]thiophene base unit via the versatile, hitherto unreported 3-[3,4-dimethyl-5-(3-nitrilopropanoyl)thieno[2,3-b]thiophen-2-yl]-3-oxopropanenitrile (4) is described.
متن کاملElectrochemical activities of some heterocyclic compounds containing benzimidazole moiety
A number of N-substituted benzimidazole derivatives have been synthesized and tested for their antibacterial activities. The chemical structures of the newly synthesized compounds were verified on the basis of spectral and elemental methods of analysis. Apart of this electrochemical analysis are performed on these derivatives. The electrochemical reduction of these compounds takes place in a si...
متن کاملOxidation of Some Biologially Active and Related Sulfur Containing Compounds
Earlier works on oxidation of sulf ides, thiols, and disulf ides with both chemical and enzymic systems are reviewed. Enzymic oxidations of thiols and disulfides are compared with their chemical oxidations with N2O and H2O2 by the use of unsymmetrical disulf ides, thiolsulfinates and O18_ tracer technique. In both enzymic oxidation and that with N2O, oxidation of disulfides to thiolsulfinates i...
