The synthesis of novel 1,2,3‐thiadiazol derivatives containing 2H‐benzo[b][1,4]oxazin‐3(4H)‐one moiety as one of the substituents has been reported. A combined application of H3PO4/(CF3CO)2Omediatedacylationfollowed by Hurd–Morireaction has been explored to synthesize these compounds. The scope and limitation of this strategy along with the reaction mechanism of the key step is discussed.
据报道合成了新型的1,2,3-噻二唑衍生物,该衍生物含有2 H-苯并[ b ] [1,4]恶嗪-3(4 H)-一个部分作为取代基之一。已经研究了结合使用H 3 PO 4 /(CF 3 CO)2 O介导的酰化反应,然后进行Hurd-Mori反应合成这些化合物的方法。讨论了该策略的范围和局限性以及关键步骤的反应机理。
