Regio- and Stereoselective Synthesis of (E)- and (Z)-Vinylic Sulfones and Their Conversion to the Corresponding Allylic Sulfones
(E)- and (Z)-vinilyc sulfones were prepared regio- and stereoselectively from 1-alkenes or 1-alkynes in high yields via iodosulfonization in AcOEt-H2O.The vinylic sulfones thus prepared were converted to the corresponding allylic sulfones by treatment wit
