arylation of 3‐substituted 1,2,4‐oxadiazoles with aryl iodides in the presence of a palladium catalyst and silver acetate is reported. This method provides a rapid, reliable way to obtain versatile 3,5‐diaryl‐1,2,4‐oxadiazole derivatives, which are common moieties of many biologically active molecules. The synthetic applications of this novel method have been demonstrated in the concise syntheses of Ataluren
据报道,在钯催化剂和乙酸银存在下,3-取代的1,2,4-恶二唑与碘代芳烃的直接C-5-H芳基化反应。该方法提供了一种快速,可靠的方法来获得通用的3,5-二芳基-1,2,4-恶二唑衍生物,这是许多生物活性分子的常见部分。这种新方法的合成应用已在Ataluren和有效的RET抑制剂Yhhu251的简明合成中得到了证明。
