Abstract:

Cyclisation of ethyl 2-ethoxymethylidene-3-oxo-3-polyfluoroalkylpropionates with 3-amino-1H-{[}1,2,4]triazole gives ethyl 7-polyfluoroalkyl-7-hydroxy-4,7-dihydro{[}1,2,4]triazolo{[}1,5-a]pyrimid ine-6-carboxylates that are subject to ring-chain isomerisation in solution, depending on the solvent and the length of the polyfluoroalkyl substituent, to yield ethyl 3-polyfluoroalkyl-3-oxo2-\{({[}1,2,4]triazol-3-yl)aminomethylidene\}prop ionates via heterocyclic ring opening at the C(7)-N(8) bond.
