two-step method was developed for the synthesis of aromatic and aliphatic sulfonamides from the corresponding sulfinates using bis(2,2,2-trichloroethyl)azodicarboxylate as the electrophilic nitrogen source. The intermediate sulfonylhydrazides were obtained in very good yields and were cleaved under reductive conditions to deliver the desired sulfonamides. A variety of substituents in the aromatic ring
开发了一种分两步的方法,使用双(2,2,2-三氯乙基)偶氮二羧酸酯作为亲电子氮源,由相应的亚磺酸酯合成芳族和脂族磺酰胺。中间体磺酰肼以非常高的产率获得,并且在还原条件下裂解以递送期望的磺酰胺。芳香环中的各种取代基以及杂环均具有良好的耐受性。
