| titleOfInvention | Fluorine-containing heterocyclic compound |
| abstract | NEW MATERIAL:A fluorine-containing heterocyclic compound shown by the formula I (Rf is fluoroalkyl; R 1 and R 2 are alkyl; X is O or S; Y is F, fluoroalkyl or dialkylamino). n EXAMPLE: A compound shown by the formula II. n USE: An intermediate for a fluoro compound showing physiological activity such as antiviral activity, etc. n PREPARATION: A fluoroacylurea shown by the formula III (Rf 1 and Rf 2 are preferably ≤5C fluoroalkyl like Rf) or a fluoroacylthiourea is subjected to a ring formation reaction of dehydrofluorination by the action of especially a base (e.g., tertiary amine such as triethylamine, etc.) to give a compound shown by the formula I. Preferably the compound shown by the formula III is produced by reacting a fluoroacylcarboxylic acid fluoride shown by the formula IV with an N,N'-dialkylurea or N,N'-dialkylthiourea shown by the formula V under dehydrofluorination condition. n COPYRIGHT: (C)1986,JPO&Japio |
