A new method for the formation of cyclic ethers and lactones is described. Dimethyl(methylthio)sulfonium fluoroborate (DMTSF) initiates formation of an episulfonium ion, which is followed by internal nucleophilic displacement to give the products in good yields.
描述了一种形成环醚和内酯的新方法。氟硼酸二甲基(甲硫基)ulf(DMTSF)引发表epi离子的形成,随后进行内部亲核取代,从而以高收率得到产物。
