7-epoxy-3,9-henicosadiene (2), all stereoisomers of (3Z)-cis-6,7-cis-9,10-diepoxy-3-henicosene [leucomalure (1)], a sex pheromone component of the Satin moth, were prepared in addition to the cis-3,4-cis-6,7-diepoxy analog (3). Specifically, MCPBA oxidation of each enantiomer of this epoxydiene yielded a mixture of four compounds, namely two diastereomeric sets of leucomalure and the positional isomer,
从光学活性 (3Z,9Z)-cis-6,7-epoxy-3,9-henicosadiene (2), (3Z)-cis-6,7-cis-9,10-diepoxy-3-henicosene 的所有立体异构体除了 cis-3,4-cis-6,7-diepoxy 类似物 (3) 之外,还制备了 [leucomalure (1)],一种缎纹蛾的性信息素成分。具体而言,该环氧二烯的每个对映异构体的 MCPBA 氧化产生四种化合物的混合物,即两组非对映异构体和位置异构体,它们可以通过配备 Chiralpak AD 柱或 Chiralcel OJ-R 柱的手性 HPLC 轻松分离。通过 2D-NMR 分析确定了它们的化学结构,并进一步证实了手性 HPLC 柱也具有很高的解析这些双环氧化物的对映异构体的能力。
