Action des hydrazines perfluoroalkylees sur les iminoesters synthese des perfluoroalkyl-3-aminothienopyrimidinones et des perfluoroalkyl-1,2,4-triazin-6-ones

Treatment of N-(2-methoxycarbonylthienyl) 1, N-(3-ethoxycarbonyl)-4,5,6,7-tetrahydrobenzothienyl 2 and N-ethoxycarbonylmethyl 3 imidates with perfluoroalkylated hydrazines yields perfluoroalkyl-3-amino[3,2-d]4(3H)thienopyrimidinones 4, perfluoroalkyl-3-amino-2-méthyl-5,6,7,8-tetrahydrobenzo[2,3-d]4(3H)thienopyrimidinones 5 and perfluoro-alkyl-1,2,4-triazin-6-ones 6. The products obtained gave information on the mechanism of cyclization. é ent of N-(2-methoxycarbonylthienyl) 1, N-(3-ethoxycarbonyl)-4,5,6,7-tetrahydrobenzothienyl 2 and N-ethoxycarbonylmethyl 3 imidates with perfluoroalkylated hydrazines yields perfluoroalkyl-3-amino[3,2-d]4(3H)thienopyrimidinones 4, perfluoroalkyl-3-amino-2-méthyl-5,6,7,8-tetrahydrobenzo[2,3-d]4(3H)thienopyrimidinones 5 and perfluoro-alkyl-1,2,4-triazin-6-ones 6.
