A variety of nonconjugated cis-olefins has been enantioselectively epoxidized with chiral ketones 2, and up to 92% ee has been obtained. The two prochiral faces of an olefin are likely stereodifferentiated by the relative hydrophobicity of the olefin substituents and/or allylic oxygen functionality.
多种非共轭顺式烯烃已与手性酮2对映选择性环氧化,获得了高达 92% 的 ee。烯烃的两个前手性面可能因烯烃取代基和/或烯丙基氧官能团的相对疏水性而立体分化。
