Abstract

(E)-and (Z)-vinylic sulfones were prepared regio-and stereoselectively from 1-alkenes or 1- alkynes in high yields via iodosulfonization in AcOEt-H 2 O. The vinylic sulfones thus prepared were converted to the corresponding allylic sulfones by treatment with DBU. Stereochemistry of the conversion was discussed.
