| Abstract: | 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. |
