本文通过Williamson反应,合成了9个双环笼状硫代磷酸酯的硫醚衍生物3a～i。以3b,3c为例研究了硫醚衍生物的还原性,并合成相应的亚砜化合物4b,4c。讨论了亚砜化合物的立体化学。
In this paper, thioether derivatives 3a ~ i of nine bicyclic cage phosphorothioates were synthesized by Williamson reaction. Taking 3b and 3c as examples, the reducibility of thioether derivatives was studied and the corresponding sulfoxide compounds 4b and 4c were synthesized. The stereochemistry of sulfoxide compounds is discussed.
