-octyn-3-ol was achieved by lipase-mediated asymmetric acetylation. The resolved (R)-alkynol was converted into (4R,9Z)-9-octadecen-4-olide, which was identical with the female sex pheromone of the currant stem girdler (Janus integer). The absolute configuration of the natural pheromone was thus established as R. (4S,9Z)-9-Octadecen-4-olide was also synthesized, and found to be pheromonally inhibitory
(±)-8-tert-butyldiphenylsilyloxy-1-octyn-3-ol 的对映异构体分离是通过脂肪酶介导的不对称乙酰化实现的。解析出的(R)-炔醇转化为(4R,9Z)-9-octadecen-4-olide,与黑醋栗茎带(Janus integer)的雌性信息素相同。天然信息素的绝对构型由此确立为 R。(4S,9Z)-9-Octadecen-4-olide 也被合成,并发现是信息素抑制。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
