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.

    Extended cavity pyrene-based iptycenes for the turn-off fluorescence detection of RDX and common nitroaromatic explosives / A. F. Khasanov [et al.] // New Journal of Chemistry. - 2017. - Vol. 41, № 6. - P2309-2320

PYRENE (CHEMICAL) -- FLUORESCENCE -- RDX (CYCLONITE)
Аннотация: Extended cavity pyrene-based iptycenes have been synthesized by using the Diels–Alder reaction between in situ generated dehydropyrenes and anthracene. The photophysical properties and the interaction of these iptycenes with nitro-explosive components were studied both in solution and in the solid state by using fluorescence spectroscopy and X-ray crystallography, respectively. Due to the presence of both the large iptycene cavity and the central pyrene core, an unprecedently high fluorescence-quenching response towards non-aromatic and non-planar 1,3,5-trinitroperhydro-1,3,5-triazine (RDX) has been observed both in solution (with an apparent Stern–Volmer constant value aKSV up to 1.53 × 103 M−1) and in the vapor phase (50–75% fluorescence quenching of the PU films doped with chemosensors). In the case of nitroaromatic explosives, nitrobenzene (NB), 2,4-DNT, TNT, and 2,4,6-trinitrophenol (TNP or picric acid, PA), pyrene-based iptycenes also demonstrate a good fluorescence-quenching response both in solutions (with apparent Stern–Volmer constant values aKSV = 0.4–8.0 × 103 M−1) and in the vapor phase (up to 90% fluorescence quenching of the PU films doped with chemosensors). The “sphere of action” fluorescence quenching model was suggested.

    Synthesis and characterization of linear 1,4-diazine-triphenylamine–based selective chemosensors for recognition of nitroaromatic compounds and aliphatic amines / E. V. Verbitskiy, Y. A. Kvashnin, E. F. Zhilina [et al.] // Dyes and pigments. - 2020. - Vol. 178. - P108344

ALIPHATIC AMINES -- FLUORESCENCE QUENCHING -- NITROAROMATIC COMPOUNDS -- PYRAZINE -- QUINOXALINE -- SOLVATOCHROMISM
Аннотация: Novel 1,4-diazine-based dyes of the D–π–A type, possessing triphenylamine as an electron-donating group, have been developed. Fluorescence studies have demonstrated that emission of these fluorophores is sensitive towards different nitroaromatic compounds and aliphatic amines, both in solutions and in a vapor phase. Moreover, these compounds can be considered as “naked-eye” fluorescent probes for solution polarity because they possess pronounced solvatochromic properties. Therefore, these compounds have to be regarded as potential multifunctional chemosensors for monitoring hazardous organic substances.

    Features of a multicomponent biginelli reaction involving 3-oxobutanoyl-containing podands, aromatic aldehydes, and 1,2,4-triazol-3-amine / E. S. Filatova, O. V. Fedorova, K. A. Chistyakov [et al.] // Chemistry of heterocyclic compounds. - 2020. - Vol. 56, № 1. - P88-91

DIHYDROPYRIMIDINE -- MONOSUBSTITUTED PODAND -- PODAND -- TRIAZOLO[1,5-А]PYRIMIDINE -- TRIAZOLO[4,3-А]PYRIMIDINE -- TUBERCULOSTATIC ACTIVITY
Аннотация: [Figure not available: see fulltext.] A reaction of 3-oxobutanoyl-containing podands with thiophene-2-carbaldehyde (or benzaldehyde) and 3-amino-1,2,4-triazole gave podands featuring a 4,7-dihydro[1,2,4]triazolo[1,5-а]pyrimidine motif. It was established that the process was accompanied by the formation of [4,3-а]-isomers, which occurred in a slight excess during the synthesis of a podand containing a phenyl group at position 7 and, on the other hand, were observed as the minor products during the synthesis of podands bearing a thiophen-2-yl substituent. Trace amounts of monosubstituted podands were also detected, containing a free hydroxy group along with the triazolodihydropyrimidine pharmacophore.

    Assembly of annulated 1,3-diazapyrenes by consecutive cross-coupling and cyclodehydrogenation of (het)arene moieties / E. V. Verbitskiy, E. M. Dinastiya, O. S. Eltsov [et al.] // Mendeleev communications. - 2020. - Vol. 30, № 2. - P142-144
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Di(het)areno[e,l][1,3]diazapyrene core was constructed by FeCl3-mediated intramolecular oxidative cyclodehydrogenation of 5-[2,6-di(het)arylphenyl]pyrimidine precursors, which in turn were obtained by the Suzuki cross-coupling of 5-(2,6-dibromophenyl)pyrimidine derivative with the corresponding (het)arylboronic acids. Molecular orbital calculations as well as redox and photophysical measurements show that the fused products are promising for organic electronic application.

    Synthesis and physicochemical and catalytic properties of composites in the Sio2–Zro2 system / A. N. Murashkevich, O. A. Alisienok, E. S. Novik [et al.] // Inorganic materials. - 2020. - Vol. 56, № 4. - P430-436
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Кл.слова (ненормированные):
ACID-BASE PROPERTIES -- CATALYSIS -- COMPOSITE -- SILICA -- SPECIFIC SURFACE AREA -- ZIRCONIA
Аннотация: Using coprecipitation, a sol–sol method, and molecular layering, we have synthesized SiO2–ZrO2 composites with SiO2 : ZrO2 ratios from 1 : 1 to 9 : 1 and a large specific surface area, which increases with growth silicon-containing component concentration. Using adsorption of Hammett indicators, we have assessed the concentration of acid–base centers in the pK range 1.3–9.6, which has been shown to vary from 68 to 160 μmol/g. Elemental analysis and IR spectroscopy data have demonstrated the presence of not only water but also nitrate ions and carbon dioxide on the surface of the samples. It has been shown that the use of nanoparticulate SiO2–ZrO2 oxides as heterogeneous catalysts—promoters for (2S,4R)-4-hydroxyprolyl-(S)-1-phenylethylamine trifluoroacetate, a chiral inducer in the asymmetric Biginelli reaction, makes it possible to raise ee (enantiomeric excess) from 39 to 68% and the reaction yield from 29 to 55%.
