Ключевые слова (''Своб.индексиров.''): triazine synthesis--1,3-dicarbonyl --isomerism
Аннотация: Azo coupling of 1,3-dicarbonyl compounds with tetrazolyl-5-diazonium chloride is used to develop a convenient one-step procedure for the synthesis of 4,7-dihydrotetrazolo[5,1-c][1,2,4]triazines. In contrast to nonfluorinated analogs, 7-hydroxy-7-polyfluoroalkyl-4,7-dihydrotetrazolo[5,1-c][1,2,4]triazines undergo a ring-chain isomerism resulting from the cleavage at the C7 - N7a bond. A distinctive feature of nonfluorinated 4,7-dihydrotetrazolo[5,1-c][1,2,4] triazines is the possibility to dehydration, which is accompanied by an azide rearrangement due to the tetrazole ring cleavage with the formation of tetrazolo[1,5-b][1,2,4]triazines

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).

Заглавие : Stereochemical aspects in the synthesis of novel N-(purin-6-yl)dipeptides as potential antimycobacterial agents
Место публикации : Amino Acids. - 2021. - Vol. 53, № 3. - С. 407-415
ББК : Г
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Ключевые слова (''Своб.индексиров.''): dipeptides--racemization--purine--coupling--nucleophilic substitution--antimycobacterial activity
Аннотация: The synthesis of purine conjugates with natural amino acids is one of the promising directions in search for novel therapeutic agents, including antimycobacterial agents. The purpose of this study was to synthesize N-(purin-6-yl)dipeptides containing the terminal fragment of (S)-glutamic acid. To obtain the target compounds, two synthetic routes were tested. The first of them is based on coupling of N-(purin-6-yl)-(S)-amino acids to dimethyl (S)-glutamate in the presence of carbodiimide coupling agent followed by the removal of ester groups. However, it turned out that this coupling process was accompanied by racemization of the chiral center of N-(purin-6-yl)-α-amino acids and in all cases led to mixtures of (S,S)- and (R,S)diastereomers (6:4). Individual (S,S)-diastereomers were obtained using an alternative approach based on the nucleophilic substitution of chlorine in 6-chloropurine or 2-amino-6-chloropurine with corresponding dipeptides as nucleophiles. The enantiomeric purity of the target compounds was confirmed by chiral HPLC. To test the assumption that racemization of the chiral center of N-(purin-6-yl)-α-amino acids occurs with the participation of nitrogen atoms of the imidazole ring via the stage of formation of a chirally labile intermediate, we obtained such structural analogs of N-(purin-6-yl)-(S)-alanine as N-(9-benzylpurin-6-yl)-(S)-alanine and N-(7-deazapurin-6-yl)-(S)-alanine. It was found that coupling of these compounds to dimethyl (S)-glutamate was also accompanied by racemization. This indicates that the imidazole fragment does not play a crucial role in this process. When testing the antimycobacterial activity of some of the obtained compounds, conjugates with moderate activity against the laboratory Mycobacterium tuberculosis H37Rv strain (MIC 3.1–6.25 μg/mL) were identified.

Аннотация: A convenient synthetic approach to the 2,2’-bipyridines, including those with a condensed cyclopentene fragment, having an aminophenyl substituent at the C5 or C6 positions is reported. The products were obtained via their 1,2,4-triazine analogs with a nitro group, by the subsequent transformation of their 1,2,4-triazine ring into a pyridine one and the reduction of the nitro group to the amino group.

Аннотация: Steric structure of fluorinated 2-arylhydrazono-3-oxo esters was studied by 1H, 19F, and 13C NMR spectroscopy and X-ray analysis. It was found that these compounds in the crystalline state and in solutions in acetone-d 6, DMSO-d 6, and CDCl3 exist as Z isomers with the ester fragment involved in intramolecular hydrogen bond with the hydrazone NH proton. Exceptions are alkyl 2-arylhydrazono-4,4-difluoro-3-oxobutanoates which exist in acetone-d 6 as mixtures of Z and E isomers, the former prevailing. Unlike fluorinated analogs, ethyl 2-(4-methylphenyl)hydrazono-3-oxobutanoate in crystal has the structure of E isomer in which intramolecular hydrogen bond is formed between the NH proton and acetyl carbonyl group. The same compound in acetone-d 6, DMSO-d 6, and CDCl3 gives rise to a mixture of Z and E isomers, the latter prevailing
