A novel entry to the synthesis of diazoacetates is disclosed. A variety of diazoacetates were synthesized from the corresponding bromoacetates by treatment with N,N'-ditosylhydrazine in moderate to high yields. Ease of operation with the stable crystalline reagent as well as a short reaction time offer a useful alternative to the conventional methods.
公开了重氮乙酸酯合成的新方法。通过用N,N′-二甲苯磺酰基肼以中等至高收率处理,由相应的溴乙酸酯合成各种重氮乙酸酯。稳定的结晶试剂易于操作,反应时间短,是常规方法的有用替代品。
