A convenient synthesis of sulfonamides from thiols and disulfides is described. In situ preparation of sulfonyl chlorides from thiols is accomplished by oxidation with 1,3-dichloro-5,5-dimethylhydantoin (DCH) under Nbenzyl-trimethylammonium chloride and water. The sulfonyl chlorides are then further allowed to react with excess amine in the same reaction vessel.
描述了从硫醇和二硫化物方便合成磺胺类药物。从硫醇原位制备磺酰氯是通过在 N苄基-三甲基氯化铵和水下用 1,3-二氯-5,5-二甲基乙内酰脲 (DCH) 氧化来完成的。然后进一步使磺酰氯在同一反应容器中与过量胺反应。
