A new process is described for preparing very pure linear alkanethiols and linear alpha,omega-alkanedithiols using a sequential alkylation of the title compound, followed by a ring closure to quantitatively give the corresponding 3-methyl[1,3]thiazolo[3,2-a]-[3,1]benzimidazol-9-ium salt and the alkanethiol derivative under mild conditions. The alkanethiol and the heteroaromatic salt are easily ...

Reaction of porphycene isothiocyanates with primary and secondary amines leads to the formation of thiazolo[4,5-c]porphycenes, with a substantial shift in the absorption and fluorescence spectra. The conjugates show fluorescence in the near-infrared and are capable of photosensitizing the production of the cytotoxic species singlet oxygen.

A highly diastereoselective annulation of simple aldehydes and 5-alkenyl thiazolones, via oxidative NHC catalysis has been developed. This strategy provides facile access to a diverse library of functionalized chiral thiazolo pyrones. Aerobic oxygen can also be applied as a secondary oxidant to avoid the use of stoichiometric organic or inorganic oxidants.

Epilepsy is the most frequnt nearological affiction and afflicts 1% about of the worlds population. Currently there is an urgent need for the development of novel anticonvulsants with higher levels of potency and lower levels of toxicity. In this paper, a series of new 6-(substituted-phenyl)thiazolo[3,2-b][1,2,4]triazole derivatives were synthesized and tested for their anticonvulsant activity ...

The series of 6,7,8,9-tetrahydro-5H-5-(2'-hydroxyphenyl)-2-(4'-substituted benzylidine)thiazolo(2,3-b)quinazolin-3(2H)-ones (4a-j) and 6,7,8,9-tetrahydro-5H-5-(2'-hydroxyphenyl)-2-(4'-substituted benzylidine)-3-(4-nitrophenyl amino)thiazoloquinazolines (5a-j) were synthesized by the reported method and evaluated for their phosphodiesterase inhibitory activity. All test compounds exhibited good ...

Symmetric and asymmetric chalcogenides of organic nature are a class organometallic compounds that widely used as intermediates in number reactions, ligands the chemistry coordination compounds, they have wide range biological activity. Diaryl tellurides, which important for formation new carbon-carbon bonds, special area organotelluric compounds. The synthesis representatives this tellurium-co...

The titled compounds were prepared by interaction of ethyl 2-(benzo[d]thazol-2-yl)acetate (3) with different arylidinemalononitrile derivatives (4a-c) in EtOH/TEA solution at room temperature. When 3 was treated with 2(ethoxymethylene)-malononitrile (4f) under same reaction conditions, the ethyl iminothiazolopyridine-4-carboxylate (6) was obtained. Ethyl (amino(methoxy)methyl)-3-(substitutedphe...
