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.
A compound and method for producing an enantiomerically enriched epoxide from an olefin using a chiral ketone and an oxidizing agent is disclosed.
