general, facile, and efficient method is presented for the synthesis of 3-substituted 1,2,4-oxadiazoles from amidoximes and triethyl orthoformate. The procedure employs an iron(III) chloride/l-proline catalytic system and the 3-substituted 1,2,4-oxadiazole products are obtained in moderate to good yields. A general, facile, and efficient method is presented for the synthesis of 3-substituted 1,2,4-oxadiazoles
摘要 提出了一种由a肟和原甲酸三乙酯合成3-取代的1,2,4-恶二唑的通用,简便而有效的方法。该方法使用氯化铁(III)/ 1-脯氨酸催化体系,并且以中等至良好的产率获得了3-取代的1,2,4-恶二唑产物。 提出了一种由a肟和原甲酸三乙酯合成3-取代的1,2,4-恶二唑的通用,简便而有效的方法。该方法使用氯化铁(III)/ 1-脯氨酸催化体系,并且以中等至良好的产率获得了3-取代的1,2,4-恶二唑产物。
