• Base-Catalyzed Intramolecular Defluorination/O-Arylation Reaction for the Synthesis of 3-Fluoro-1,4-oxathiine 4,4-Dioxide
  作者：Jinlong Qian、Gaoxi Jiang、Lei Kang、Jinlong Zhang、Huameng Yang

  DOI：10.1055/a-1387-8862

  日期：2021.5

  A novel process involving base-catalyzed intramolecular defluorination/O-arylation of readily available α-fluoro-β-one-sulfones was realized and provided a series of 3-fluoro-1,4-oxathiine 4,4-dioxide derivatives in good to excellent yields. Unlike traditional defluorination reactions with stoichiometric base as the deacid reagent, this process is triggered by a catalytic amount of base (TMG: tetramethylguanidine)

  实现了一种新的方法，该方法涉及碱催化易得的α-氟代-β-砜的分子内脱氟/ O-芳基化反应，并提供了一系列3-氟-1,4-氧代草氨酸4,4-二氧化物衍生物。优异的产量。与传统的以化学计量的碱作为脱酸剂的脱氟反应不同，此过程是由催化量的碱（TMG：四甲基胍）触发的，分子筛既充当吸附剂以去除HF酸，又充当活化剂以帮助CF键断裂。
