The first aryl iodide catalyzed intramolecular C–H amination of phenylurea has been disclosed for high-efficiency synthesis of benzimidazolone derivatives in excellent yields (up to 97%) by an operationally simple one-step organocatalytic oxidative process. Fluorinated protic alcohols can efficiently accelerate the conversion of this transformation. The straightforward method has good functional group
已经公开了第一个芳基碘催化苯脲的分子内 C-H 胺化,用于通过操作简单的一步有机催化氧化过程以优异的收率(高达 97%)高效合成苯并咪唑酮衍生物。氟化质子醇可以有效地加速这种转变的转化。直接的方法具有良好的官能团耐受性,并且可以使用廉价且易于获得的催化剂以高熟练度进行。
