SYNTHESIS -- 2-AZIDO-5-NITROPYRIMIDINE -- AZIDO-TETRAZOLE TAUTOMERISM
Аннотация: We describe the synthesis of 2-azido-5-nitropyrimidine and its azido-tetrazole tautomerism in various solvents and in the crystalline state. It was established that on interacting with N-nucleophiles the attack occurred at the C-2 carbon atom. The O- and S-nucleophiles attacked C-4 position of pyrimidine ring, resulting in tetrazole ring closure

    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

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.

    Addition of the oxirane derivatives to CO2 catalyzed by Lewis bases under mild conditions / I. S. Gabov, V. A. Kuznetsov, I. S. Puzyrev, A. V. Pestov // Russian chemical bulletin. - 2021. - Vol. 70, № 6. - P1118-1123

CYCLIC CARBONATES -- CARBON DIOXIDE -- LEWIS BASES -- QUANTUM CHEMICAL CALCULATIONS
Аннотация: The addition of the oxirane derivatives to CO2 was found to occur without Lewis acid involvement but requires the presence of the Lewis base. The reaction was carried out at atmospheric pressure by CO2 bubbling through the starting ether in the presence of a source of halide anion or trichloroacetate anion, which provides the formation of ethylenecarbonate derivatives in preparative amounts. The reactivity of halide anions in the addition of the studied oxirane derivatives to CO2 decreases in the order I− > Br− > Cl− > F− >> Cl3CCOO−. The quantum chemical calculations of the reaction of CO2 with epichlorohydrin show that the reaction consists of consecutive processes of nucleophilic addition and nucleophilic ipso-substitution, which explains the catalytic effect of the Lewis bases and the order of their activity.

    Adsorption properties of mesoporous carbon synthesized by pyrolysis of zinc glycerolate / I. S. Puzyrev, E. I. Andreikov, V. A. Osipova [et al.] // Russian chemical bulletin. - 2021. - Vol. 70, № 5. - P805-810

Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Mesoporous carbon of lamellar morphology was synthesized by the thermal decomposition of zinc glycerolate in an inert atmosphere followed by the removal of zinc oxide from the ZnO/C composite. The obtained material was characterized by scanning electron microscopy, Raman spectroscopy, and low-temperature adsorption of nitrogen. Mesoporous carbon is remarkable for a high adsorption rate of methylene blue dye from aqueous solutions with the maximum adsorption capacity toward the dye equal to 1680 mg g−1.

Кл.слова (ненормированные):
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.

    Nucleophilic aromatic substitution of hydrogen and related reactions [Electronic resource] / V. N. Charushin, O. N. Chupakhin // Mendeleev Communications. - 2007. - Vol. 17, № 5. - P249-254
ББК 54
Рубрики: ХИМИЧЕСКИЕ НАУКИ
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.

Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Data on new methods for the synthesis of fused azines by nucleophilic attack on the unsubstituted carbon atom of azines and nitroarenes are generalised. The review surveys tandem reactions of azines with binucleophiles comprising nucleophilic addition AN–AN nucleophilic addition–substitution AN–SipsoN, and nucleophilic substitutions SHN–SipsoN and SHN-SHN. Intramolecular SHN reactions of azines and nitroarenes and other methods for the synthesis of fused heterocycles based on SHN nucleophilic substitution are also discussed
