Аннотация: New synthetic routes to trifluoromethylated N-heterocycles based on condensations of 2-methoxy-2-methyl-5-(trifluoromethyl)furan-3(2H)-one with bifunctional N-nucleophiles are described. For the first time, trifluoromethyl-containing pyrazoles, pyrazolines and isoxazolines bearing hydrazone or oxime groups could be obtained by a one-pot strategy based on reactions of 5-(trifluoromethyl)furan-3(2H)-one with two equivalents of the corresponding hydrazines or hydroxylamine in the presence of an acid. The interaction of furan-3(2H)-one with ureas proceeded under mild conditions to furnish 1H-furo[2,3-d]imidazol-2(3H)-one derivatives in good yield. Further, a trifluoromethyl-containing quinoxaline derivative was obtained by condensation of furan-3(2H)-one with ortho-phenylenediamine.

Заглавие : Azapyrene-based fluorophores: synthesis and photophysical properties

Аннотация: Azapyrenes are the nitrogen isosteres of pyrene. Based on theoretical and experimental studies, electron–acceptor azapyrene domains may be considered as convenient scaffolds for constructing a large variety of “push–pull” π-conjugated chromophores with pronounced ICT properties. Over the past decade, due to the unrelenting interest in functional materials and modern methodologies such as cross-coupling, peri-annulation, direct C–H-functionalization, etc., methods for the synthesis of aryl(alkyl) K-functionalized azapyrenes and other derivatives have been developed, and their photophysical and electrochemical properties have been studied. This short review aims at critical analysis of the best known/modern methods for the preparation of functionalized azapyrene derivatives, as well as an assessment of their photophysical/electrochemical properties in comparison with the structural and electronic properties of the parent pyrene.

Ключевые слова (''Своб.индексиров.''): 1,2,4-triazines--nitrogen-containing heterocycles
Аннотация: Among the six-membered nitrogen-containing heterocycles the 1,2,4-triazines have attracted the attention of chemists for a long time. This is due to the fact that many 1,2,4-triazine derivatives are biologically active and are used in medicine and agriculture. Moreover, 1,2,4-triazines are of chemical interest. They proved to be very susceptible to attack by all kinds of nucleophiles, leading to the addition, and subsequently either substitution or cyclization, and ring transformation. This continuing and lively interest in this area of heterocyclic chemistry has produced a great number of publications and patent applications. This chapter concentrates on the behavior of monocyclic 1,2,4-triazines in reactions with C-, N-, 0-, and S-nucleophiles, because the important features of general character established for simple 1,2,4-triazines can evidently be applied to other derivatives including condensed 1,2,4-triazines.

Заглавие : Chemical elements in medicine
Место публикации : Herald of the Russian academy of sciences. - 2020. - Vol. 90, № 2. - С. 229-238
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.

Ключевые слова (''Своб.индексиров.''): synthetic methods--cross-cou­pling--nitrogen heterocycles
Аннотация: The combination of the Suzuki–Miyaura cross-coupling and nucleophilic aromatic substitution of hydrogen reactions is a versatile tool for the syntheses of 4-(1R-pyrrol-2-yl)- and 4-(1R-indol-3-yl)-5-(hetero)aryl-substituted pyrimidines from commercially available 5-bromopyrimidine. The SNH [AE, (addition–elimination)] and SNH [AO, (addition–oxidation)] reactions of 5-bromopyrimidine with pyrroles and indoles were studied by gas chromatography–mass spectrometry. The structures of the intermediate σH adducts as well as the pyrrole-(hetero)arylpyrimidine and indole-(hetero)arylpyrimidine dyads were established for the first time by X-ray crystal structure analysis

Ключевые слова (''Своб.индексиров.''): quinoxalinum salts--c-nucleophiles --azinium cations
Аннотация: In reactions with quinoxalinium salts in alcoholic-base media indan-1,3-dione acts as a C nucleophile, adding at the 2 or 3 position of the heterocycle to give the corresponding ylidene derivatives; attack by the nucleophile at the C(3) atom (the Β position relative to the quaternary nitrogen atom) is preceded by addition of alcohol at the a position. Dissociative substitution at the C(2) atom in 2-alkoxy-3-(1,3-dioxoindan-2-ylidene)-1,2,3,4-tetrahydroquinoxalines by another nucleophile makes it possible to regard lyate complexes as probable intermediates in cyclizations of 1,4-diazinium salts with dinucleophiles.

Ключевые слова (''Своб.индексиров.''): nitroaromatic explosives--fluorescence quenching--pyridines--pyrazine--pyrimidines--triazines
Аннотация: Highly sensitive and selective detection of nitro containing high energy organic compounds such as picric acid (PA), 2,4,6-trinitrotoluene (TNT) and 2,4-dinitrotoluene (DNT) has become a challenging task due to concerns over national security, criminal investigations and environment protections. Among various known detection methods, fluorescence sensors have gained special attention in recent time. The family of fluorescent sensors based on push-pull systems that incorporate nitrogen heterocycles as an electron-withdrawing group have a growing interest due to their high sensitivity, selectivity and easy tuning. The fluorescent sensors discussed in this review are classified and organized according to used azaheterocyclic scaffold, their functionality and their ability to detect of nitroaromatics by fluorescence quenching.

Аннотация: Fluorinated enaminoketones, a new type of ligands, bearing two independent coordination centers (polyether's and fluorinated enaminoketones fragments) have been obtained. The crystal structure of the Cu(II) complex of 1,5-bis-[2-(4`,4`,4`-trifluoro-1`-methyl-3`oxo-but-1`-enylamino)-phenoxy]-3-oxapentane (10) has been elucidated by X-ray crystallography. The results obtained show that the complex 10 consists of two crystallographically independent molecules C26H24CuF6N2O5 (A and B), and the metal atom in the complex 10 has four-coordinated arrangement, as a polyhedron with a distorted square with two nitrogen and two oxygen atoms located in corners.
