PROCESS FOR PRODUCTION OF OPTICALLY ACTIVE EPOXY COMPOUND

摘要

[PROBLEMS] To provide a process for producing an optically active epoxy compound. [MEANS FOR SOLVING PROBLEMS] Disclosed is an industrially useful process for producing an optically active epoxy compound. In the reaction between an unsaturated compound and an oxidizing agent in the presence of an optically active titanium-salen complex, an optically active titanium-salalen complex or an optically active titanium-salan complex, it is found that the addition of a buffering agent or a buffer solution to the reaction system enables to reduce the decomposition of the catalyst, reduce the amount of the catalyst used, and reduce the production of a by-product compared to a conventional process, and can produce a high-quality, optically active epoxy compound in high chemical yield and with high optical purity.
