(E)- and (Z)-vinylic 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 with DBU. Stereochemistry of the conversion was discussed.
(E)- 和 (Z)- 乙烯基砜是通过在 AcOEt-H2O 中碘磺化以高产率由 1-烯烃或 1-炔烃以区域和立体选择性制备的。如此制备的乙烯基砜通过用DBU处理转化为相应的烯丙基砜。讨论了转化的立体化学。
