fluorodesulfurization of 3-aryl-2-phenylthio 2H-benzo[b][1,4]oxazine derivatives was successfully carried out using various N-halogenosuccinimides as oxidizing reagent in the presence of Et 3 N·3HF to provide the corresponding monofluorinated products in excellent yields. Selective fluorodesulfurization of the corresponding pyrido[3,2-b][1,4]oxazine derivatives was also achieved similarly.
以各种N-卤代琥珀酰亚胺为氧化剂,在Et 3 N·3HF存在下,成功地对3-芳基-2-苯硫基2H-苯并[b][1,4]恶嗪衍生物进行选择性氟脱硫,得到相应的单氟化产物以优异的产量。相应的吡啶并[3,2-b][1,4]恶嗪衍生物的选择性氟脱硫也同样实现。
