An efficient one-pot method has been developed for the synthesis of 1,2,4-oxadiazoles through a one-pot reaction of nitriles with hydroxylamine hydrochloride in the presence of magnesia-supported sodium carbonate followed by reaction with acyl halides under solvent-free conditions using microwave irradiation. This method is easy, rapid and good yielding.
已开发出一种有效的一锅法,该方法通过在氧化镁负载的碳酸钠存在下,腈与盐酸羟胺一锅反应,然后在无溶剂下与酰卤反应,来合成1,2,4-恶二唑使用微波照射的条件。该方法简便,快速且产率高。
