different isomers, it may use these differences to discriminate flowers of S. latifolia hosts from flowers of non‐host plants. To investigate the question whether the moths have in their antennae one olfactory receptor or several different receptors for the detection of the single lilac aldehyde isomers, (2S,2′S,5′S)‐lilac aldehyde was diastereoselectively synthesized. (2S,2′S,5′S)‐Lilac aldehyde and its
单萜丁香醛 (=2-(5-ethenyl-5-methyloxolan-2-yl)propanal) 是一种广泛使用的花香。丁香醛从夜间活动的植物物种中大量释放出来,它对夜间活动的飞蛾传粉者具有很强的吸引力,例如哈德纳 (Hadena bicruris),它是 Silene latifolia 的授粉种子捕食者。丁香醛具有三个立体中心,可以出现在八种立体异构体中,在 H. bicruris 中诱导不同的触角反应。立体异构体的分布模式因植物物种而异,如果 H. bicruris 具有不同的受体来检测不同的异构体,则可以利用这些差异来区分 S. latifolia 寄主的花和非寄主植物的花。为了研究飞蛾的触角中是否有一个嗅觉受体或几种不同的受体来检测单个丁香醛异构体,(2S,2'S,5'S)-丁香醛是非对映选择性合成的。(2S,2'S,5'S)-丁香醛及其异构体混合物在 H. bicruris
