efficient synthetic route to construct a variety of 3-amidated quinoxalin-2(1H)-ones was developed via transition-metal free direct oxidative amidation of quinoxalin-2(1H)-ones with amidates usingSelectfluor reagent as a mild oxidant. This protocol features mild reaction conditions, operational simplicity, broad substrate scope, and good to excellent yields.
一种实用的和有效的合成路线来构造各种3-酰胺化喹喔啉-2(1 H ^ -酮)的开发是通过喹喔啉-2-的过渡金属无直接氧化酰胺化(1 ħ) -酮使用的Selectfluor试剂作为酰胺化温和的氧化剂。该方案的特点是反应条件温和,操作简便,底物范围广,收率高至优异。
