A convenient synthesis of ( E)-conjugated polyene sulfonyl derivatives with excellent stereospecificity

摘要

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 onlytransproducts.
