An effective and convenient method has been developed for the preparation of 1-unsubstituted 1H-indazoles via CH amination of N-acetylhydrazones in the presence of a catalytic amount of manganese dioxide under microwave irradiation. This new method featured easy operation and relatively short reaction-time.
已经开发了一种有效且方便的方法,用于在催化量的二氧化锰的存在下,在微波辐射下,通过N-乙酰基hydr的C H胺化反应,制备1-未取代的1 H-吲唑。该新方法操作简便,反应时间相对较短。
