  Structural Probing of Ketone Catalysts for Asymmetric Epoxidation

  摘要：

  A series of chiral ketones derived from carbohydrates were investigated as catalysts for the asymmetric epoxidation. Fructose-derived ketones are found to be efficient catalysts. The studies show that the structural requirements for the ketone catalysts are very stringent and different types of olefins may require ketones with different structural arrangements. The current study allows us to further understand the chiral ketone catalyzed asymmetric epoxidation and provides some insight for the development of new catalysts.

  Regio- and stereoselective iodinations under controlled Garegg conditions were performed on vicinal diols and contiguous triols located on pyranose templates. P- D -Fructo- or psicopyranose-based diols were selectively iodinated at C-5 or C-4, respectively, to afford the L -sorbo or D -tagato iodohydrins. In contrast, the related triols only underwent selective iodination at C-5. Application of the

  在受控的 Garegg 条件下，对位于吡喃糖模板上的邻二醇和连续三醇进行区域选择性和立体选择性碘化。基于 P-D-果糖或吡喃吡喃糖的二醇分别在 C-5 或 C-4 处选择性碘化，以提供 L-山梨糖或 D-塔格托碘醇。相比之下，相关的三醇仅在 C-5 处进行选择性碘化。将该方法应用于 D-葡糖苷和 D-吡喃半乳糖苷导致分别在 C-3 或 C-4 处选择性碘化，以提供 D-allo 或 D-葡糖碘醇。

  A regio- and stereoselective iodination has been performed on vicinal diols located on ketopyranose templates using the controlled-Garegg conditions. 3-O-Benzy1-1,2-O-isopropylidene-beta-D-fructo- or psicopyranoses (1 or 4) were selectively iodinated, respectively, at C-5 or C-4 of the ketoses to afford the L-sorbo or D-sorbo iodohydrins.
