three components (i.e., heteroarene, alcohol, and CHCl3). The copper additive was confirmed to simultaneously promote the reaction in three pathways: oxidant cracking, single electron transfer, and alcoholysis. By means of this protocol, various functionalized furancarboxylates and other heteroarenecarboxylates were facilely obtained in moderate to good yields.
我们报告了通过一步一步的铜介导的三个成分(即杂芳烃,醇和CHCl3)的一步反应,将呋喃及其他杂芳烃直接烷氧基羰基化的有效方法。证实了铜添加剂可同时通过三个途径促进反应:氧化剂裂解,单电子转移和醇解。通过该方案,可以容易地以中等至良好的产率获得各种官能化的呋喃羧酸盐和其他杂芳基羧酸盐。
