TEMPLATE SYNTHESIS -- CHALCONE PODAND -- CROWN ETHERS
Аннотация: A new type of intramolecular cyclization of 1,5-bis[2-(E-3-oxo-3-phenylprop-1-enyl)-phenoxy]-3-oxapentane with 3-aminotriazole promoted by potassium ions was discovered. A cascade mechanism for the formation of crownophane with 4,7-dihydro[1,2,4]triazolo[1,5-a]-pyrimidine fragment was suggested. Effects of oligooxyethylene fragment of the chalcone podand and acid-base catalysis on the selectivity of the cyclocondensation processes and degree of oxidation of triazolopyrimidine fragments were studied. The product structures were confirmed by IR, 1H and 13C NMR spectroscopy and X-ray diffraction study

Аннотация: C-Adducts of 5-(het)aryl-2,3-dicyano-1-pyrazinium salts containing a residue of a 1,3-dicarbonyl compound at position 6 can be involved in the cyclization with hydrazine hydrate giving rise to pyrazino[2,3-c]pyridazines along with the expected pyrazole derivatives. The reactions of the same ?H-adducts with hydroxylamine unexpectedly afforded triazacyclopenta[a]indene derivatives. The crystallographic data on the three-dimensional structures of new polycyclic compounds were obtained

    Three-component cyclization of hydroxylamino-substituted quinoline with reactive methylene compounds and formaldehyde: new method for the synthesis of 7-(isoxazolidin-2-yl)-6-fluoroquinolones [Electronic resource] / N. N. Mochul`skaya, L. P. Sidorova, V. N. Charushin // Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). - 2002. - Vol. 51, № 11. - P2106-2108

Аннотация: A one-step procedure was developed for the synthesis of new 6-fluoro-7-(isoxazolidin-2-yl)-4-oxo-1,4-dihydroquinolines. The procedure is based on the 1,3-dipolar cycloaddition of the azomethine oxide and 1,1-disubstituted alkenes, which are generated in situ from 6-fluoro-7-hydroxylamino-4-oxo-1,4-dihydroquinoline-3-carboxylic acid and CH-active compounds (dialkyl malonates, ethyl acetoacetate), respectively, in the presence of formaldehyde at 100—120 °C

Аннотация: Reaction of 3-aryl-1,2,4-triazines with S,N-dinucleophilic N-(het)arylthioureas in acetic anhydride at room temperature affords the cyclization products, tetrahydrothiazolo[4,5-e]-[1,2,4]triazines in good yields. The structure of the heterocyclic system thus formed was confirmed by X-ray diffraction analysis.

Аннотация: The Suzuki cross-coupling of 1,2-bis(6-iodo-2-methylbenzo[b]thiophen-3-yl) hexafluorocyclopentene and (het)arylboronic acids depending on the reaction conditions affords bis- or mono-adducts. The latter on next cross-coupling with different boronic acid give unsymmetrical dihetarylethenes. Spectral-kinetic studies of the photoinduced cyclization of the compounds obtained were performed

ACRYLIC ACID DERIVATIVE -- PYRAZOLE -- TUBERCULOSTATIC AGENT
Аннотация: A rapid development of the resistance of drugs and their toxic and adverse reactions suggest that new antituberculous drugs should be designed. Of the greatest importance is isoniazid resistance. Testing new compounds (IIa, b) has established that the minimum inhibitory concentration of the drug (IIa), 0.39 microgram/ml suppresses the growth of Mycobacterium tuberculosis (MBT) in the macrophages up to 50%, that of the drug (IIb), 1.56 micrograms/ml, causes death in 25% of cases, which is indicative of the high activity of compounds (IIa, b) against MBT
