Аннотация: 1-Phenyl-4,5-dihydroxy-4,5-bis(trifluoromethyl)imidazolidin-2-one was synthesized by the reaction of perfluorobiacetyl with phenylurea. Reaction of the former with urea was studied in comparison with the similar interaction of N-methyl-substituted and unsubstituted analogues. N-phenylimidazolidine was shown to yield trifluoromethylated imidazooxazol and hydantoin when heated with urea in dimethylacetamide, in contrast to unsubstituted analog which gives trifluoromethylated glycoluril under the same conditions. The similar reaction in dioxane led to isomerization of cis-isomers of the starting imidazolidines to corresponding trans-isomers. Structure of the reaction products was proved by IR, 1H, 13C and 19F spectroscopy, HR mass spectrometry, elemental analysis and XRD analysis.

Заглавие : Functionalized trifluoromethyl-containing lithium β-diketonate in the synthesis of homo- and heteronuclear complexes of rare-earth metals

Ключевые слова (''Своб.индексиров.''): β-diketonates--lanthanides--19f nmr spectroscopy--mass spectrometry
Аннотация: The reactions of functionalized lithium CF3-β-diketonate (LiL) with trivalent rare-earth metal salts in methanol afford homobinuclear and heterobi(tri)nuclear complexes depending on the nature of the transition metal and anion (chlorides, nitrates, and acetates). In the cases of lanthanum(III) and cerium(III), homoleptic complexes [(LnL3)2] are isolated (CIF files CCDC nos. 2031097 (Ia) and 2031102 (Ib)). The reaction of LiL with praseodymium(III) nitrate gives the new trimetallic structure [(LiPrL3)(LiL)(NO3)(H2O)2] (CIF file CCDC no. 2031103 (II)), and the replacement of nitrate by chloride gives [(PrL3)(LiL)(H2O)] (CIF file CCDC no. 2031104 (IIIa)). Regardless of the nature of the anion of the salt in the series from neodymium(III) to ytterbium(III) and yttrium(III), Ln–Li β-diketonates [(LnL3)(LiL)(solv)] (solv is H2O and MeOH) are formed, and their structures are characterized by X-ray structure analysis (CIF files CCDC nos. 2031099 (IIIb), 2031100 (IIIc), 2031098 (IVa), 2031096 (IVc), 2031094 (IVf), 2031101 (IVg), and 2031095 (IVh)). The equilibrium of the diketonate isomeric forms in a solution of deuterated dimethyl sulfoxide is studied by 19F NMR spectroscopy, and the qualitative composition of the polynuclear complexes is determined by mass spectrometry.

Ключевые слова (''Своб.индексиров.''): copper(ii)--diketonates--cytotoxic activity--antimicrobial activity
Аннотация: Copper(II) complexes with 1,1,1-trifluoro-4-(4-methoxyphenyl)butan-2,4-dione (HL1) were synthesized and characterized by elemental analysis, FT-IR spectroscopy, and single crystal X-ray diffraction. The biological properties of HL1 and cis-[Cu(L1)2(DMSO)] (3) were examined against Gram-positive and Gram-negative bacteria and opportunistic unicellular fungi. The cytotoxicity was estimated towards the HeLa and Vero cell lines. Complex 3 demonstrated antibacterial activity towards S. aureus comparable to that of streptomycin, lower antifungal activity than the ligand HL1 and moderate cytotoxicity. The bioactivity was compared with the activity of compounds of similar structures. The effect of changing the position of the methoxy group at the aromatic ring in the ligand moiety of the complexes on their antimicrobial and cytotoxic activity was explored. We propose that complex 3 has lower bioavailability and reduced bioactivity than expected due to strong intermolecular contacts. In addition, molecular docking studies provided theoretical information on the interactions of tested compounds with ribonucleotide reductase subunit R2, as well as the chaperones Hsp70 and Hsp90, which are important biomolecular targets for antitumor and antimicrobial drug search and design. The obtained results revealed that the complexes displayed enhanced affinity over organic ligands. Taken together, the copper(II) complexes with the trifluoromethyl methoxyphenyl-substituted β-diketones could be considered as promising anticancer agents with antibacterial properties

Заглавие : Polyfluoroalkylated antipyrines in Pd-catalyzed transformations
Место публикации : RSC Advances. - 2021. - Vol. 11, № 56. - С. 35174-35181
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: In the direct C–H arylation with arylhalogenides in the presence of Pd(OAc)2, trifluoromethyl-containing antipyrine reacts very slowly and incompletely owing to the low nucleophilicity of its C4 center. However, it was effective in modifying polyfluoroalkyl-substituted 4-bromo- and 4-iodo antipyrines by the Suzuki and Sonogashira reactions. It was established that using Pd2(dba)3 as catalyst and XPhos as phosphine ligand was the optimal catalytic system for the synthesis of 4-aryl- and 4-phenylethynyl-3-polyfluoroalkyl-antipyrines. Moreover, iodo-derivatives as the initial reagents were found to be more advantageous compared to bromo-containing analogs. It was found that 4-phenylethynyl-5-CF3-antipyrine has a moderate activity against the influenza virus A/Puerto Rico/8/34 (H1N1) and 4-iodo-5-CF3-antipyrine reveals a weak activity against the vaccine virus (strain Copenhagen) and bovine diarrhea virus (strain VC-1).

Ключевые слова (''Своб.индексиров.''): chroman-4-ones --triketone-like ligands--binuclear complexes
Аннотация: The present work is to investigate of binding properties of chelating triketone-like ligands, which are able to forming of binuclear complexes. The studied compounds are able to exist in cyclic or 'close form' (phenyl substituted or unsubstituted 2-hydroxy-2-(trifluoromethyl)chroman-4-ones) as well as in their associated 'open form' (phenyl substituted or unsubstituted 1,1,1-trifluoro-4-(2-hydroxyphenyl)butan-2,4-diones). In this paper there is good evidence for the compounds are being in solid in 'close form' (pre-ligands), whereas in basic solutions and when involved in metal ion coordination sphere they are being in 'open form' (ligands). Protolytic equilibria of the compounds in aqueous ethylene glycol solutions were studied. Schemes of acid-base equilibria of these compounds were proposed. Apparent ionization constants of compounds containing electron-donor and electron-acceptor substituents in the benzene ring were determined using spectrophotometric method. The binding properties of 1,1, 1-trifluoro-4-(2-hydroxyphenyl)butan-2,4-dione towards Cu(II), Ni(II) and Co(II) were studied. The formation of 2:2 metal-ligand complexes was observed. X-ray analysis gives evidence the formation of complexes in which the ratio metal to ligand can be 1:2 and 2:2. Similar to beta-triketones the studied ligands tends to formation of binuclear complexes with transition metal ions

Ключевые слова (''Своб.индексиров.''): 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 series of alkyl 2-Arylhydrazinylidene-3-oxo-3-polyfluoroalkylpropionates was synthesized and their inhibitory activity with respect to porcine liver carboxylesterase (CaE, EC 3.1.1.1), human erythrocyte acetylcholinesterase (AChE, EC 3.1.1.7), and horse serum butyrylcholinesterase (BChE, EC 3.1.1.8) was studied. The molecular docking method was used to study the binding mode of the compounds in the active site of CaE. It was found that compounds containing the trifluoromethyl group in the third position of carbonyl chain are highly effective and selective inhibitors of CaE with nanomolar IC50 values, which agrees well with the results of molecular docking.

Аннотация: In this paper we report the synthesis of novel S-alkenyl derivatives of 5-(trifluoromethyl)-4H-1,2,4-triazole-3-thiol via alkenation reaction with different alkenyl halides. Reaction between the resulting S-alkenation products and iodine proceeds regiospecifically to give new fused fluorine- and iodine-containing [1,2,4]triazolo[3,4-b][1,3]thiazine heterocyclic systems. The structure of synthesized compounds was confirmed by mass spectra, IR, 1H, 13C and 19F NMR spectroscopy including 2D 1H–13C HSQC, 1H–1H COSY, 1H–13C HMBC correlations, elemental analysis and single-crystal X-ray diffraction study. --------------------------------------------------------------------------------

Ключевые слова (''Своб.индексиров.''): thiadiazines--tautomeric structures --4h-tautomer
Аннотация: Fluorinated 2-amino-5-phenyl-1,3,4-thiadiazines were obtained for the first time. A study of their tautomeric structures revealed that trifluoromethyl-containing 1,3,4-thiadiazines exist as the 4H-tautomer in both solutions and the solid state, while their monofluoroaryl analogs exist as the 6H-tautomer
