CESIUM -- EPOXIDE -- FURAN DERIVATIVE -- PERFLUORO COMPOUND
Аннотация: Perfluorotetrahydrofuran-2-carboxylic acid was converted through a series of transformations into perfluoro-2,3-dihydrofuran and perfluoro-2,5- dihydrofuran; likewise, from (2-perfluorotetrahydrofuryl)difluoroacetic acid 2-trifluoromethylpentafluoro-2,3-dihydrofuran was obtained. Perfluoro-2,3- dihydrofuran and 2-trifluoromethylpentafluoro-2,3-dihydrofuran underwent isomerization into perfluoro-2,5-dihydrofuran and 2-trifluoromethylpentafluoro- 2,5-dihydrofuran by the action of cesium fluoride. Treatment of perfluoro-2,5-dihydrofuran with SbF5 resulted in ring opening and formation of cis-perfluoro-2-butenoyl fluoride, while 2- trifluoromethylpentafluoro-2,3-dihydrofuran was converted into 2-trifluoromethylpentafluoro-2,5-dihydrofuran under the same conditions. Perfluoro-3,4-epoxytetrahydrofuran and 2-trifluoromethyl-3,4-epoxypenta- fluorotetrahydrofuran containing fused oxirane and tetrahydrofuran rings were synthesized by reactions of perfluoro-2,5-dihydrofuran and 2- trifluoromethylpentafluoro-2,5-dihydrofuran, respectively, with sodium hypochlorite.

Аннотация: The reaction of 5-(het)aryl-2,3-dicyano-1-ethylpyrazinium salts with phenol derivatives affords relatively stable dihydropyrazines, whereas the reactions of 6-(het)aryl-1,2,5-oxadiazolo[3,4-b]pyrazin-4-ium protic salts, depending on the phenol structure, result in products of nucleophilic substitution of hydrogen or open-chain transformation products: benzo[b]furan-substituted derivatives. The crystallographic data on the spatial structure of all types of the synthesized products were obtained

A simple and effective approach to acetal or acyl substituted CF3-pyrazoles, 5,5′-bis(trifluoromethyl)-3,3′-bipyrazole, and, to 5-trifluoromethylfuran-3-ones is presented.

NITROGEN HETEROCYCLES -- FLUORINE -- OXYGEN HETEROCYCLES
Аннотация: New synthetic routes to trifluoromethylated N-heterocycles based on condensations of 2-methoxy-2-methyl-5-(trifluoromethyl)furan-3(2H)-one with bifunctional N-nucleophiles are described. For the first time, trifluoromethyl-containing pyrazoles, pyrazolines and isoxazolines bearing hydrazone or oxime groups could be obtained by a one-pot strategy based on reactions of 5-(trifluoromethyl)furan-3(2H)-one with two equivalents of the corresponding hydrazines or hydroxylamine in the presence of an acid. The interaction of furan-3(2H)-one with ureas proceeded under mild conditions to furnish 1H-furo[2,3-d]imidazol-2(3H)-one derivatives in good yield. Further, a trifluoromethyl-containing quinoxaline derivative was obtained by condensation of furan-3(2H)-one with ortho-phenylenediamine.

Аннотация: A facile two-step synthetic approach to fluorinated and non-fluorinated 5-aryl-4-(5-nitrofuran-2-yl)-pyrimidines from readily available 5-bromo-4-(furan-2-yl)pyrimidine has been developed. All synthesized compounds were screened in vitro for their antibacterial activities against twelve various bacterial strains. It is demonstrated that some of these compounds exhibited significant antibacterial activities against strains Neisseria gonorrhoeae and Staphylococcus aureus, comparable and even higher with that commercial drug Spectinomycin.

Аннотация: The Buchwald–Hartwig cross-coupling of 5-bromo-4-(furan-2-yl)pyrimidine with various anilines afforded the corresponding new 5-(arylamino)pyrimidines, the reaction being accelerated by microwave irradiation. Most of the obtained compounds proved to possess a high bacteriostatic in vitro effect against Mycobacterium tuberculosis H37Rv, Neisseria gonorrhoeae, and Staphylococcus aureus including Methicillin-resistant strain, which is stronger than that of the commercial drug Spectinomycin.
