A number of macrocyclic diamides have been synthesized from the reaction of a diacid dicarboxylic dichloride with primary diamino compound in the presence of magnesium oxide-silica gel at room temperature in good yields. Using urea and thiourea as well as diamines to produce the corresponding macrocycles in the range of 52–56% yields are also included in this paper. One of the major advantages of this
在室温下在氧化镁-硅胶存在下,由二酸二羧酸二氯化物与伯二氨基化合物的反应以高收率合成了许多大环二酰胺。本文还包括使用尿素和硫脲以及二胺生产相应的大环化合物,其收率范围为52-56%。该方法的主要优点之一是无机固体的简单再生,并且可以在不降低活性的情况下经过数个循环再利用。
