A large number of novel 3-(heterocyclylsulfonyl)propanoic acids and their amide derivatives were prepared in good yields and excellent purity starting from the corresponding heterocyclic compounds. At first, chlorosulfonates were generated by reaction of initial heterocycles with various sulfonating and chlorinating agents followed by their conversion into sodium sulfinates. Treatment of sulfinates
从相应的杂环化合物开始,以高收率和高纯度制备了大量新型 3-(杂环基磺酰基)丙酸及其酰胺衍生物。首先,氯磺酸盐是通过初始杂环与各种磺化剂和氯化剂反应生成的,然后将它们转化为亚磺酸钠。用丙烯酸处理亚磺酸盐可以顺利得到一系列磺酰丙酸盐,它们可用作制备大量相应甲酰胺衍生物的方便试剂。
