method for the construction of fluorinated pyrimidinones based on the reaction of cyanodifluoromethyl-substituted amines with isocyanates is described. The use of ortho-iodophenylisocyanate in this reaction followed by copper catalyzed intramolecular amination affords fluorinated fused heterocycles – 4-fluoropyrimido[1,6-a]benzimidazol-1(2H)-ones.
描述了基于氰基二氟甲基取代的胺与异氰酸酯的反应来构造氟化嘧啶酮的方法。在该反应中使用邻-碘苯基异氰酸酯,然后在铜催化的分子内胺化反应中得到氟化的稠合杂环-4-氟嘧啶[1,6 - a ]苯并咪唑-1(2 H)-ones。
