(4R,9Z)-Octadec-9-en-4-olide, the female sex pheromone of the currant stem girdler (Janus integer), was synthesized in gram quantities by employing Sharpless asymmetric dihydroxylation (AD) and Jacobsen hydrolytic kinetic resolution (HKR). Crystalline (R)-hexadec-7-yne-1,2-diol (87 % ee), obtained by AD and purified by recrystallization, was converted into (R)-1,2-epoxyhexadec-7-yne (87 % ee), which
(4R,9Z)-Octadec-9-en-4-olide 是黑醋栗茎带(Janus integer)的雌性信息素,通过采用 Sharpless 不对称二羟基化 (AD) 和 Jacobsen 水解动力学分辨率 (HKR) 以克量合成)。通过 AD 获得并通过重结晶纯化的结晶 (R)-hexadec-7-yne-1,2-diol (87% ee) 转化为 (R)-1,2-epoxyhexadec-7-yne (87% ee) ),经 HKR 进一步纯化至 96% ee。基于 hex-5-en-1-ol(11 个步骤),环氧化物以 14% 的总产率转化为目标内酯。(© Wiley-VCH Verlag GmbH & Co.
