    Stereoselective hetero-Diels–Alder reaction of 3-nitro-2-trihalomethyl-2H-chromenes with 2,3-dihydrofuran and ethyl vinyl ether under solvent-free conditions [Text] / V. Yu. Korotaev, V. Ya. Sosnovskikh, M. A. Barabanov, E. S. Yasnova, M. A. Ezhikova, M. I. Kodess, P. A. Slepukhin // Tetrahedron. - 2010. - Vol. 66, № 6. - P1404-1409

Аннотация: 3-Nitro-2-trifluoro(trichloro)methyl-2H-chromenes undergo heterodiene cycloaddition to 2,3-dihydrofuran and ethyl vinyl ether under solvent-free conditions producing novel cyclic nitronates with high stereoselectivity and in good yields. 3,6-Dinitro-2-trifluoromethyl-2H-chromene reacts with two molecules of ethyl vinyl ether to give the tandem [4+2]/[3+2] cycloaddition adduct in 48% yield. The stereochemistry of the products was established based on 2D COSY, NOESY, HSQC, and HMBC experiments and an X-ray diffraction study

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: Epoxy-anhydride polymers based on N,N,O-triglycidyl-p-aminophenol and isomethyltetrahydrophthalic anhydride were synthesized in the presence of new active modifiers, polyfluoroalkyl glycidyl ethers. The kinetics of the reactions of the modifiers with the anhydride were studied by differential scanning calorimetry and IR spectroscopy. The physicomechanical characteristics, glass transition points, and water absorption of the polymers were determined.

    Complexes of crown ethers with perfluorocarboxylic acids and their thermal decarboxylation [Electronic resource] / A. V. Podol'skii, T. G. Khonina, O. V. Koryakova, M. I. Kodess // Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). - 1993. - Vol. 42, № 6. - P1052-1055
ББК 54
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Crown ethers form strong proton-acceptor complexes with CF3COOH or C4F9COOH that undergo thermal decarboxylation at 200–260 °C which results in 60–80% of CF3H or C4F9H (including up to 20 % of a mixture of C4F8). Critical parameters of the process were determined in relation to the temperature and amount of crown ether. The relative activities of different crown ethers in decarboxylation were also established. A scheme is proposed that explains the effect of the structure of crown ethers on this reaction. The data obtained substantiate the view that the topological correspondence concept is insufficient to explain the ability of crown ethers to form complexes with cat

In the presence of potassium cations, the reaction is intramolecular and gives crown ether containing the ?-truxin-type cyclobutane fragment (anti, head-to-head) as the major product.

It is based on the Wagner oxidation or NBS-mediated epoxydation of 2-vinylpyridine, and the Schwenk-Papa reduction of 1-(pyridin-2-yl)ethan-1,2-diol, accompanied by fractional crystallization of a diastereo-meric mixture of the target produc
