A facile synthesis of various allyl sulfonamides based on imidation of allyl sulfides with chloramine‐T and subsequent [2,3]‐sigmatropic rearrangement has been achieved without metal catalysts. The reaction completes smoothly within 10 min, providing excellent yields in environment friendly solvent of alcohol. Functional groups such as bromine, hydroxyl, protected amido and aldehyde are tolerant under
在没有金属催化剂的情况下,已经实现了基于烯丙基硫化物的氯胺-T酰亚胺化和随后的[2,3]-σ重排的轻松合成各种烯丙基磺酰胺的方法。反应在10分钟内顺利完成,在环境友好的乙醇溶剂中提供优异的收率。在这种条件下,溴,羟基,受保护的酰胺基和醛等官能团是可以耐受的。
