A general and efficient procedure for p-toluenesulfonic acid-catalyzed iodination of isoquinolin-1(2H)-ones with N-iodosuccinimide at room temperature is described. This method provides an alternative way of constructing C–I bonds, affords various 4-iodoisoquinolin-1(2H)-ones in moderate to good yields, and shows a broad substrate scope and good functional group tolerance.
描述了在室温下对甲苯磺酸催化异喹啉-1(2 H)-酮与 N-碘代琥珀酰亚胺碘化的一般有效程序。该方法提供了另一种构建 C-I 键的方法,以中等至良好的产率提供各种 4-iodoisoquinolin-1(2 H )-one,并显示出广泛的底物范围和良好的官能团耐受性。
