    6-Polyfluoroalkylated 2-thiouracils in the synthesis of pyrimido[2,1-b][1,3,5]thiadiazines by the double Mannich reaction [Electronic resource] / O. G. Khudina, A. E. Ivanova, Ya. V. Burgart, V. I. Saloutin, M. A. Kravchenko // Journal of Fluorine Chemistry. - 2013. - Vol.147. - P31-35

ALIPHATIC AND AROMATIC AMINES -- ETHYLENEDIAMINE -- FORMALDEHYDE
Аннотация: 6-Polyfluoroalkyl-2-thiouracils react with formaldehyde and primary amines in EtOH (MeCN) at 2-mercapto and 3-amino groups to yield pyrimido[2,1-b][1,3,5] thiadiazines via the multicomponent double Mannich reaction. The structure of 3-benzyl-8-nonafluorobutyl-3,4-dihydro-2H,6H-pyrimido[2,1-b][1,3,5] thiadiazin-6-one was studied by the X-ray diffraction analysis. The use of ethylenediamine in these reactions yields 3,3′-ethane-1,2-diyl- bis(pyrimido[2,1-b]thiadiazinone) as a result of the bis-double Mannich cyclocondensation. 8-Polyfluoroalkyl-pyrimido[2,1-b]thiadiazines exhibit weak tuberculostatic activity

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

4,4,4-TRIFL UORO-3,3-DIHYDROXY-2-(HYDROXYIMINO)BUTAN-1-ONES -- POLYFL UOROALKYL2-HYDROXYIMINO-1,3-DIKETONES -- 1-METHYL-4-NITROSOPYRAZOLES -- MYCOSTATIC ACTIVITY
Аннотация: We studied different approaches to the synthesis of polyfluoroalkyl-containing 1-methyl-4-nitrosopyrazoles, which are based on the cyclization of 4,4,4-trifluoro-3,3-dihydroxy-2-hydroxyimino-1-R-butan-1-ones or 2-hydroxyimino-1,3-diketones with methylhydrazine and on a one-pot sequential treatment of 1,3-diketones with sodium nitrite and methylhydrazine. It was found that the regioselectivity of the formation of 1-methyl-4-nitrosopyrazoles is affected by the steric factors of 1,3-dicarbonyl reagents. The study of the mycostatic effect of 4-nitrosopyrazoles showed that the introduction of a bulky polyfluoroalkyl or tert-butyl substituent leads to a decrease in their activity.

    Condensation of fluoroalkyl-containing 1,2,3-trione 2-arylhydrazones with methylamine [Electronic resource] / E. V. Shchegol'kov, Ya. V. Burgart, P. A. Slepukhin, O. N. Kazheva, V. I. Saloutin // Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii). - 2007. - Vol. 43, № 12. - P1788-1796
ББК 54
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Fluoroalkyl-containing 1,2,3-trione 2-arylhydrazones react with methylamine in different ways, depending on the substrate structure. Arylhydrazones having a short fluoroalkyl substituent (RF = CF3, HCF2CF2) react at the carbonyl group adjacent to the nonfluorinated substituent to give 3-alkyl(aryl)-2-aryldiazenyl-3-methylamino-1-polyfluoroalkylprop-2-en-1-ones. Arylhydrazones with a long-chain fluoroalkyl group (RF = C3F7 and longer) and a bulky nonfluorinated group take up methylamine molecule at the carbonyl group linked to the fluorinated substituent, and the subsequent haloform reaction yields N-methyl-2-arylhydrazono-3-oxobutanamides. Both types of products are formed in reactions of methylamine with 1,2,3-triketone 2-arylhydrazones having a long fluoroalkyl group and methyl group at the other carbonyl group. Template condensation of fluoroalkyl-containing 1,2,3-trione 2-arylhydrazones with methylamine over Ni(II) template gives bis[3-alkyl(aryl)-1-polyfluoroalkyl-3-methylamino-2-aryldiazenylprop-2-en-1-onato-N,N?]-nickel(II), regardless of the size of the fluoroalkyl substituent. The same complexes and their copper analogs can be obtained by treatment of 3-alkyl(aryl)-2-aryldiazenyl-3-methylamino-1-polyfluoroalkylprop-2-en-1-ones with the corresponding metal salts

    Effect of the nature of a fluorinated substituent on the synthesis of functionalized 1,3-diketones / Y. S. Kudyakova, A. Y. Onoprienko, Y. O. Edilova [et al.] // Russian chemical bulletin. - 2021. - Vol. 70, № 4. - P745-752

Аннотация: The synthesis of alkali metal and copper(II) 1-polyfluoroalkyl-4,4-dimethoxypentane-1,3-dionates is reported. The subsequent treatment of these compounds with oxalic acid or ethylenediaminetetraacetic acid disodium salt affords functionalized 1,3-diketones. The nature of the polyfluoroalkyl substituent was found to affect the conditions of the Claisen condensation and the stability of the acetal group in acidic medium.
