PODANDES -- X-RAY DIFFRACTION ANALYSIS -- ACETIC ACID -- ORGANIC ACIDS
Аннотация: 1,8-Bis(diisothiosemicarbazido)-3,6-dioxaoctane have been synthesized by subsequent treatment of 2,2 -(ethylenedioxy)bisethylamine with carbon disulfide, sodium chloroacetate, and hydrazine hydrate. 1,8-Bis- (diisothiosemicarbazido)-3,6-dioxaoctane has reacted with lithium 1,1-difluoropenta-2,4-dionate in glacial acetic acid to yield 1,8-bis[5R*,5 R*(5-hydroxy-5-difluoromethyl-4,5-dihydro-3-methyl-1H-pyrazol-1-yl)-1-carbothioamido]-3,6-dioxaoctane. The molecular and crystal structure of the product has been determined by X-ray diffraction analysis.

N-METHYLTETRAHYDROQUINOXALINES -- PYRROLE -- IMIDAZOLE
Аннотация: 1H and 13C NMR spectral data for 21 N-methyltetrahydroquinoxalines annelated with furan, pyrrole, imidazole or thiazole rings are reported. Unambiguous assignments of the ring junction 13C resonances were made on the basis of selective decoupling experiments and with the aid of one-bond and long-range 13C–1H coupling constants. The effects of five-membered heterocycles on the 1H and 13C chemical shifts of the ring junction hydrogen and carbon atoms are considered. Values of one-bond 1J(CH) and vicinal 3J(HH) coupling constants between the ring junction protons are also discussed as a diagnostic means for structural elucidation of tetrahydroquinoxalines condensed with five-membered heterocycles.

    Synthesis and properties of azines functionalized graphene with extremely high adsorptive ability to Eu3+ ions / O. N. Chupakhin, A. A Musikhina, I. A. Utepova [et al.] // Flatchem. - 2022. - Vol. 33. - P100348
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: In this work, a versatile synthetic protocol for obtaining of new promising carbon materials based on the C–C coupling of graphenide lithium species with azaaromatic compounds (1,10-phenanthroline, phenyl-1,2,5-oxadiazolo[3,4-b]pyrazine) has been suggested. It was shown that more electrophilic oxadiazolopyrazine gave the product with high degree of graphene functionalization and demonstrated non-isomorphic properties. At the same time, phenanthrolinyl graphene has less functionalization degree due to a lower electrophilicity of azine. However, the large size of pores between organic residues in phenanthrolinyl graphene allows adsorbing almost 10% of Eu3+. The mesurment of adsorption isotherm showed an extremely high affinity of phenanthrolinylgraphene to Eu (III) ions in netural or alkaline conditions, and the obtained hybrid material could work at least 5 sorption/desorption cycles. The structures of azine-graphene dyads were verified by complex of modern physicochemical analyses methods (the Raman spectroscopy, FTIR, XPS, SEM, EDS and TGA analyses).

    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

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%.

BETA-LACTAM ANTIBIOTICS -- BORON NEUTRON CAPTURE THERAPY -- FLUOROQUINOLONES -- HETEROCYCLES
Аннотация: A brief review of chemical elements, compounds from which find application in medicine, ranging from the commonly occurring organogenic elements (carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorus), composing the structure of proteins and nucleic acids of the cells of living organisms and determining the genetic transmission, to native rarely encountered organic fluorine compounds, synthetic derivatives of which have become firmly ingrained in the arsenal of modern pharmaceutical drugs, is given. Strong emphasis is put on metalloproteins, which play a significant role in the biochemistry of vitally essential processes, as well as metal compounds that are widely used in medicine. Of particular importance are the chemical elements and the isotopes, compounds of which are employed in nuclear medicine for diagnostics and treatment of a wide range of diseases, oncological and cardiovascular in particular.

    A simple one pot synthesis of condensed 1,2,4-triazines by using the tandem AN-SNipso and SNH-SNipso reactions [Text] / O. N. Chupakhin, G. L. Rusinov, D. G. Beresnev, V. N. Charushin, H. Neunhoeffer // Journal of Heterocyclic Chemistry. - 2001. - Т. 38, № 4. - P901-907
ББК 54
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: A new synthetic approach to condensed 1,2,4-triazines based on using the tandem AN-SNipso and SNH-SNipso reactions has been developed. 5-Methoxy-3-penyl-l,2,4 1,2,4-triazine and its N1-methyl quaternary salt were found to react with C,N-, C,O- and N,N?-bifunctional nucleophiles (m-phenylenediamine, resorcinol, semicarbazide and ureas) into triazacarbazoles, benzofuro[2,3-e][1,2,4]-triazines, and 6-azapurine derivatives. In all cases nucleophiles attack first the unsubstituted C-6 carbon of the triazine ring, while the final stage is replacement of the methoxy group affording cyclization products.

Аннотация: The classical concept of nucleophilic aromatic substitution (SNAripso) has been complemented with a new synthetic methodology (SNH), enabling one to build new carbon–carbon C(sp2)–C(sp3), C(sp2)–C(sp2) and C(sp2)–C(sp) or carbon–heteroatom C(sp2)–X (X is O, N, P, S, halogen) bonds through nucleophilic displacement of hydrogen in an aromatic ring.
