Oxidation of substituted imidazoles with modified Fenton's reagent (Fe(II), ascorbic acid, EDTA and H2O2) in aqueous solution at pH 5 -7 in the presence of inorganic orthophosphate gives high yields of an unknown bound phosphate, in the case of 2-methylimidazole up to 3 5 % based on inorganic phosphate. The dependence of the yields on reaction parameters and the hydrolytic behaviour of the comp...

The three imidazole antimycotics clotrimazole, miconazole, and ketoconazole all inhibit the demethylation of lanosterol to ergosterol, resulting in inhibition of growth of Saccharomyces cerevisiae; this is a fungistatic action. At higher concentrations clotrimazole and miconazole are fungicidal, whereas ketoconazole is not. The fungicidal action reflects direct membrane damage by the imidazoles...

A short and efficient synthesis of 1,4-disubstituted imidazoles has been developed which provides the desired products with complete regioselectivity. This protocol allows preparation of compounds which are challenging to prepare by current literature methods in a regioselective fashion, a sterically and electronically diverse range of N-substituents being accessible. The sequence involves an u...

a  convenient  and  efficient  one-pot  four-component  synthesis  of  1,  2,  4,  5-tetrasubstituted  imidazoles  using  nano  tio2  as  a  recyclable  catalyst  is  reported.  the results  show  that  the  methodology  has  several  advantages  such  as  low  loading  of catalyst,  excellent  yield,  short  reaction  time,  operational  simplicity  and  solvent-free conditions.

A series of new tetrasubstituted imidazoles 2-phenyl-3-(1, 4, 5-triphenyl-1H-imidazol-2-yl)-1H-indole derivatives substituted with –F, Cl, Br, I,-OCH3 and -NHCOCH3 were synthesized using a multicomponent reaction. The compounds were obtained in good yields by easy workup and with high purity

2-Imidazolines and imidazoles have been accessed by an aza-Wittig sequence featuring novel N-acylation methodology for sulfonamides and optimized conditions for ring closure.

Nickel(0) catalysts were used to produce substituted imidazoles in good to high yields using benzonitrile, p-substituted benzonitriles and 4-cyanopyridine as starting materials.

The synthesis of small molecule based 1,3,5-trisubstituted benzenes for photo-mediated capture of human carbonic anhydrase II with visualisation by fluorescence is described.
