SYNTHESIS -- ANTIVIRAL ACTIVITY
Аннотация: Methods for the synthesis of fluorinated pyrido[1,2-a]benzimidazoles have been developed, and a series of such compounds has been obtained and studied for biological activity. In particular, 5,6-difluoro-2-cyanobenzimidazole (II) was synthesized for the first time using the reaction of 1,2-diamino-4,5-difluorobenzole (I) with cyanoacetic ether. Pyrido[1,2-a]benzimidazoles (III, IV) were obtained via condensation of benzimidazole II with diethylethoxymethylene malonate and ethyl acetoacetate. The synthesized pyrido[1,2-a]benzimidazoles (III–XIII) were subjected to screening on a culture of Vero cells for antiviral activity and cytotoxicity with respect to ortho-poxviruses that are pathogenic for humans. ??

Аннотация: Transformations of phenylacetylene and tert-butylacetylene in the presence of copper and copper oxide (Cusub2/subO, CuO) nanopowders prepared by gas-phase condensation of copper in argon were studied. The reaction of phenylacetylene with copper oxide nanopowders having different phase compositions in the absence of a solvent at room temperature resulted in oxidative condensation of phenylacetylene and complex formation of the condensation product. The complex undergoes decomposition by the action of acids, bases, and compounds capable of forming complexes. According to the X-ray diffraction data, one of the products is a new “parquet” modification of diphenyldiacetylene. Under analogous conditions, tert-butylacetylene gave rise to a complex mixture of products among which di- tert-butyldiacetylene was identified by gas chromatography-mass spectrometry. No copper complexes with the tert-butylacetylene condensation products were detected.

From the ratio of isomers formed it follows that the mesomeric effect of a fluorine atom in 1,2-phenylenediamines is comparable with the influence of an aminosubstituent

Аннотация: Carbon-encapsulated Ni and Cu nanoparticles with a core/shell structure were synthesized by levitational gas condensation (LGC). Methane (CH4) gas was used to coat the surface of the Ni and Cu nanoparticles. The Ni particles had a core diameter of 10 nm, and were covered by 2–3 nm thin carbon layers. In the case of Cu, the particles had a core diameter of 30 nm, and multi-shells with a thickness of 2–3 nm. Biginelli reaction in the presence of l-proline and Ni encapsulated nanoparticles was carried out to change the ratio between stereoisomers in favor of the S-enantiomer for 3,4–dihydropyrimidine (DHPM) with an excess of about 18%

The formylation of these indolo[3,2-b]carbazoles with dichloromethyl alkyl esters catalysed by Lewis acids leads to the formation of the corresponding 2,8-diformyl derivatives. Applicability of this formylation method for modification of indolo[3,2-b]carbazoles bearing electron-rich aromatic substituents at C-6 and C-12 has also been demonstrated. The Knoevenagel condensation of 2,8-dialdehydes with active methylene nitriles has been studied.

Аннотация: Two novel dyes IK-1,2 bearing the 8-alkyl-8H-thieno[2,3-b]indole unit as an electron-donating part of the push-pull system have been designed and prepared, as promising sensitizers for solar cells. The key steps of the synthesis involve the crotonic condensation of 1-alkylisatins with 2-acetylthiophene, followed by reduction of the C=C double bond and further cyclization through the Paal-Knorr reaction with the Lawesson reagent, thus leading to the formation of 2-(thien-2-yl) substituted thieno[2,3-b] indole derivatives. The optical and electrochemical properties of these dye's have been investigated by using spectrophotometry and cyclic voltammetry respectively, while their photovoltaic performance was evaluated by a device fabricatien study. The DSSCs based on IK-1 and IK-2 have demonstrated an efficiency of eta = 0.37% (FF = 73%) and eta = 0.7g% (FF = 69%) under 100 mW cm(-2) simulated AM 1.5G solar irradiation, respectively.

ALDOL-CROTONIC CONDENSATION -- LAWESSON'S REAGENT -- ISATIN
Аннотация: A short and robust approach for the synthesis of 2-(hetero)aryl substituted thieno[2,3-b]indoles from easily available 1-alkylisatins and acetylated (hetero)arenes has been advanced. The two-step procedure includes the "aldol-crotonic" type of condensation of the starting materials, followed by treatment of the intermediate 3-(2-oxo-2-(hetero)arylethylidene) indolin-2-ones with Lawesson's reagent. The latter process involves two sequential reactions, namely reduction of the C=C ethylidene double bond of the intermediate indolin-2-ones followed by the Paal-Knorr cyclization, thus affording tricyclic thieno[2,3-b]indoles.

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.
