A convenient synthesis of (E)-conjugated polyene sulfonyl derivatives with excellent stereospecificity
Yu, Chunyan,Lv, Zhongwen,Xu, Sheng,Zhang, Jun
, p. 3234 - 3237 (2018)
A highly selective synthesis of conjugated polyene sulfonyl derivatives is described via the elimination of disulfonyl chloride with readily accessible raw material dihaloalkane. The protocol offers a convenient way to form sulfonamides, sulfonates and even sulfones. Furthermore, this method was manipulated under mild condition with simple operation in high yield to afford only trans products.
