The Sc(III)-catalyzed [2,3]-sigmatropic rearrangement of sulfonium ylides derived from azoalkenes has been established. Owing to the absence of a carbenoid intermediate, this protocol represents the first non-carbenoid variant of the Doyle-Kirmse reaction. Under mild conditions, a variety of tertiary thioethers have been readily prepared in good to excellent yields.
本文建立了 Sc(III)催化的氮杂环丁烯衍生的砜叶立德的[2,3]-σ重排反应。由于不存在碳烯中间体，该方案代表了 Doyle-Kirmse 反应的首例非碳烯变体。在温和条件下，各种叔硫醚可以以良好至优异的产率轻易制备。
