Место публикации : RSC Advances. - 2022. - Vol. 12, № 7. - С. 4042-4046
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Iron(II) and iron(III) salts of strong acids form iron glycerolates on heating at 180 °C with glycerol in the presence of an equivalent amount of alkali. Individual iron(III) glycerolate was obtained for the first time. When Fe3O4 magnetic nanoparticles were heated with glycerol, an iron(III) glycerolate shell was formed on their surface.

Ключевые слова (''Своб.индексиров.''): 6-chloropurine--heterocyclic amines--antiviral activity--influenza a and b viruses
Аннотация: A number of novel amides were synthesized by coupling of 6-[(9H-purin-6-yl)amino]hexanoic acid to heterocyclic amines. The antiviral activity of the obtained compounds, as well as of purine conjugates in which 7,8-difluoro-3-methyl-3,4-dihydro-2H-1,4-benzoxazine is linked to position 6 of purine through a fragment of ɷ-amino acids with varying lengths of polymethylene chains against influenza A and B viruses was studied in vitro. Purine derivatives have been shown to have moderate activity against influenza A (H1N1) virus. The antiinfluenza activity and cytotoxicity of conjugates with 7,8-difluoro-3-methyl-3,4-dihydro-2H-1,4-benzoxazine depend on the length of the linker fragment.

Заглавие : HPLC separation of 2-aryloxycarboxylic acid enantiomers on chiral stationary phases
Место публикации : Russian chemical bulletin. - 2021. - Vol. 70, № 5. - С. 900-907
ББК : Г
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: The possibility for separating enantiomers of a number of practically significant 2-aryloxycarboxylic acids was studied by normal- and reversed-phase HPLC on popular chiral stationary phases. The best separation parameters were achieved on the chiral phases with the polysaccharide base Chiralcel OD-H and Chiralpack AD under the normal-phase HPLC conditions. The (S)- and (R)-enantiomers of 2-(1-naphthyloxy)- and 2-(2-iodophenoxy)propionic acids with enantiomeric excess ee 99% were isolated using preparative chiral HPLC.

Заглавие : Assembly of annulated 1,3-diazapyrenes by consecutive cross-coupling and cyclodehydrogenation of (het)arene moieties
Место публикации : Mendeleev communications. - 2020. - Vol. 30, № 2. - С. 142-144
Предметные 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.

Ключевые слова (''Своб.индексиров.''): 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.

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.

Ключевые слова (''Своб.индексиров.''): pyrimidine scaffold--perimidine systems--boronic acids
Аннотация: A convenient synthetic route to novel 7-​substituted benzo[f]​thieno[3,​2-​h]​quinazoline and 8-​substituted benzo[g,​h]​dithieno[2,​3-​e:3',​2'-​j]​perimidine systems, bearing the fused pyrimidine ring, has been advanced. A com. available 5-​bromopyrimidine was used as the starting material to obtain various polycyclic systems through the sequence of nucleophilic arom. substitution of hydrogen (the SNH reaction)​, Suzuki cross-​coupling and oxidative photocyclization. Evidence for the structure of benzo[g,​h]​dithieno[2,​3-​e:3',​2'-​j]​perimidines has been obtained by X-​ray crystallog. anal. MO calcns. (DFT)​, as well as redox and optical measurements for all new compds. have been performed. The data show that the reported polycyclic systems have potential for use in org. electronic applications. The synthesis of the target compds. was achieved using 5-​bromo-​4-​(2-​thienyl)​pyrimidine and (phenyl)​boronic acids as starting materials.

Ключевые слова (''Своб.индексиров.''): fused thiophene--pyrrole rings--fischer indolization reaction
Аннотация: A convenient approach to ladder-type 6H-benzo[4',5']thieno[2',3':4,5]thieno[3,2-b]indoles, e.g., I (X-rays single crystal structure shown)​, bearing various substituents in both terminal benzene rings has been developed. The protocol suggested for prepg. these N,S-​heteroacenes is based on using easily available reagents, such as cinnamic acids and arylhydrazines, which can be involved in the Fischer indole synthesis, as the key step. A similar condensed system of 12H-​benzo[4'',​5'']​thieno[2'',3'':4',5']​thieno[2',3':4,5]​thieno[3,2-b]indole, bearing six rings, has also been obtained.
