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.
各种非共轭顺式烯烃已被手性酮 2 对映选择性环氧化,最高获得 92%ee。烯烃的两个前手性面可能通过烯烃取代基和/或烯丙基氧官能团的相对疏水性来立体区分。
