Treatment of N-(2-methoxycarbonylthienyl) 1, N-(3-ethoxycarbonyl)-4,5,6,7-t
etrahydrobenzothienyl 2 and N-ethoxycarbonylmethyl 3 imidates with perfluor
oalkylated hydrazines yields perfluoroalkyl-3-amino[3,2-d]4(3H)thienopyrimi
dinones 4, perfluoroalkyl-3-amino-2-methyl-5,6,7,8-tetrahydrobenzo[2,3-d]4(
3H)thienopyrimidinones 5 and perfluoro-alkyl-1,2,4-triazin-6-ones 6. The pr
oducts obtained gave information on the mechanism of cyclization. (C) 2000
