We disclose the synthesis of 3-arylquinoxalin-2-ones from o-phenylenediamines and readily available arylacetates. The method harnesses the selective oxidative property of elemental sulfur in the presence of amine base catalyst and DMSO. The reactions are operationally simple and tolerate a wide range of functional groups.
我们公开了从邻苯二胺和容易获得的芳基乙酸酯合成3-芳基喹喔啉-2-酮。该方法在胺碱催化剂和 DMSO 存在下利用元素硫的选择性氧化特性。该反应操作简单并且耐受多种官能团。
