对映体纯环氧乙烯基砜可作为各种立体和区域特异性氧化和亲核官能化反应的高效底物。这些材料可以很容易地转化为环状和非环状六碳链段。 3a、b 的亲核环氧化反应随后由钯 [0] 催化,可得到差异保护的芳烃二醇 21 和 22。
Enantiopure epoxy vinyl sulfones serve as highly effective substrates for a variety of stereo- and regiospecific oxidation and nucleophilic functionalization reactions. These materials can be easily transformed to cyclic and acyclic six-carbon segments. Nucleophilic epoxidation of3a,bfollowed by palladium[0] catalysis enables access to differentially protected arene diols21and22.
