R 30 Reaction of Fluoro-containing 3-Oxoesters with Benzaldehyde [Electronic resource] / M. V. Pryadeina, O. G. Kuzueva, Ya. V. Burgart, V. I. Saloutin // Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii). - 2002. - Vol. 38, № 2. - P224-231 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Fluorinated 3-oxoesters in reactions with benzaldehyde depending on conditions afford either 2-benzylidene-3-fluoroalkyl-3-oxoesters or 3,5-dialkoxycarbonyl-2,6-dihydroxy-2,6-difluoroalkyl-4-phenyltetrahydropyrans. The latter were also obtained by treating 3-oxoesters with 2-benzylidene-3-oxoesters. Pentafluorobenzoylacetate with benzaldehyde furnishes 3,5-diethoxycarbonyl-2-pentafluorophenyl-4-phenyl-7,8,9,10-tetrafluoro-4,5-dihydrobenzo[b]oxacin-6-one \\\\Expert2\\nbo\\Russian Journal of Organic Chemistry\\2002, 38 (2), 224.pdf |
