controlled oxidation of N‐substituted 1,2,3,4‐tetrahydroisoquinolines is developed for the synthesis of 3,4‐dihydroisoquinolin‐1(2H)‐ones and isoquinolin‐1(2H)‐ones. The present method feature's a broad substrate scope, good functional group tolerances, and the products were prepared in good to excellent yields. The developed methodology further demonstrated in the synthesis of isoindolo[2,1‐b] isoquinolin‐5(7H)‐one
N-取代的1,2,3,4-四氢异喹啉的可见光玫瑰孟加拉TBHP介导的受控氧化被开发用于合成3,4-二氢异喹啉-1(2 H)-one和异喹啉-1(2 H)-个。本方法的特点是底物范围广,官能团耐受性好,并且制备的产物具有良好的产率。所开发的方法学在异吲哚并[2,1-b]异喹啉-5(7 H)-one(拓扑异构酶-I抑制剂)的合成中得到了进一步证明。
