Antipin // Journal of Fluorine Chemistry. - 2002. - Vol. 17, № 1. - P1-7 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Fluoroalkylcontaining 3-oxo esters react with aldehydes to form 2-benzylidene-3-fluoroacyl-esters or 4-aryl(alkyl)-3,5-dialkoxycarbonyl-2,6-dihydroxy-2,6-di(fluoroalkyl)tetrahydropyranes depending on the conditions. Ethyl pentafluorobenzoylacetoacetate with benzaldehyde affords 3,5-diethoxy-carbonyl-4-phenyl-2-pentafluorophenyl-7,8,9,10-tetrafluoro-4,5-dihydrobenzo[b]oxacin-6-one |
