A Ni‐catalyzed C−F bond functionalization of unactivated aryl fluorides with oxazoles as coupling partners was developed. Various arylated oxazoles could be obtained in moderate to good yields in the presence of Ni(cod)2/IMes catalytic system. A rapid synthesis of natural product texaline was also demonstrated using this protocol. This transformation could be potentially utilized in regioselective
已开发了以恶唑为偶合伴侣的未活化芳基氟化物的Ni催化C-F键官能化。在Ni(cod)2 / IMes催化体系存在下,可以以中等至良好的产率获得各种芳基化的恶唑。使用该方案还证明了天然产物texaline的快速合成。该转化可潜在地用于后期合成应用中恶唑基的区域选择性引入。
