(11S,12S,13S)-(9Z,15Z)- and (11R,12S,13S)-(9Z,15Z)-11-Hydroxy-12,13-epoxy octadecadienoic acids, self defensive substances against the rice blast disease, were synthesized enantioselectively by employing the Sharpless asymmetric epoxidation reaction of the unsymmetrical divinylcarbinol, as a key step.
(11S,12S,13S)-(9Z,15Z)-和(11R,12S,13S)-(9Z,15Z)-11-羟基-12,13-环氧十八碳二烯酸是一种防御稻瘟病的自卫物质,通过利用Sharpless不对称环氧化反应处理不对称
二烯丙基醇作为关键步骤,实现了具有对映选择性地合成。
