A new anode strategy for accessing xanthen-9-azoles via an electrochemical C(sp)-H/N-H cross-coupling of xanthenes with azoles is described. This reaction proceeds efficiently with a broad scope of both xanthenes and N-H-free azoles under metal- and additional oxidant-free conditions and represents a new access to direct incorporation of important N-heterocycle units into the resulting xanthenes.
描述了一种通过电化学使呫吨与唑类进行C(sp)-H/N-H交叉偶联来制备呫吨-9-唑类的新阳极策略。该反应在无金属和无额外氧化剂的条件下，对多种呫吨类和无N-H的唑类均能高效进行，为将重要的N-杂环单元直接引入所得呫吨类化合物提供了一种新方法。
