dc.description.abstract | Substituované 3-(fluoracyloxy)chinolin-2,4(1H,3H)-diony, mezi něž patří 3-(fluorjodacetoxy)deriváty reagují s triethyl-fosfitem za vzniku produktu Perkowovy reakce nebo odpovídajícího 4-ethoxychinolin-2(1H)-onu. V obou reakcích je jako odstupující skupina poprvé pozorován fluorkarboxylátový anion. Toto pozorování omezuje využití intramolekulární Hornerovy-Wadsworthovy-Emmonsovy syntézy k modifikaci chinolin-2,4(1H,3H)-dionů uzavřením fluorovaných but-2-enolidových kruhů. | cs |
dc.description.abstract | Substituted 3-(fluoroacyloxy)quinoline-2,4(1H,3H)-diones including 3-(fluoroiodoacetoxy) derivatives react with triethyl phosphite to afford either the product of the Perkow reaction or the corresponding 4-ethoxyquinolin-2(1H)-one. In both reactions, the fluorocarboxylate anion acts as the first observed leaving group. This observation restricts the application of the intramolecular Horner-Wadsworth-Emmons synthesis to modify quinoline-2,4(1H,3H)-diones by the annulation of fluorinated but-2-enolide rings. | en |
