4-oxadiazolin-2-ones (IIIa-u) by a single-step reaction with bromine in acetic anhydride. In the preliminary screening of all these compounds, the halogen-substituted derivatives have shown antimicrobial activities equal to those of the standard drugs used.
通过与溴在乙酸酐中的一步反应,将3-芳基sydnones(Ia-u)转化为相应的3-芳基-5-甲基-1,3,4-恶二唑啉-2-酮(IIIa-u)。在所有这些化合物的初步筛选中,卤素取代的衍生物已显示出与所用标准药物相同的抗微生物活性。
