As shown by synthesis and enantioselective gas chromatography, males and females of the caddisfly species Potamophylax latipennis and Potamophylax cingulatus produce (1R,3S,5S,7S)-1-ethyl-3,5,7-trimethyl-2,8-dioxabicyclo[3.2.1]octane, while Glyphotaelius pellucidus produces 1,3-diethyl-4,6-dimethyl-2,7-dioxabicyclo[2.2.1]heptane, having either the (1S,3S,4R,6S) or (1R,3R,4S,6S)-configuration. As shown
如合成和对映选择性气相色谱法所示,the蝇科植物波达莫克斯拉蒂彭尼斯和铃木波莫斯的雄性和雌性产生(1 R,3 S,5 S,7 S)-1-乙基-3,5,7-三甲基-2, 8-dioxabicyclocyclo [3.2.1]辛烷,而Glyphotaelius pellucidus产生1,3-二乙基-4,6-二甲基-2,7 - dioxabicyclocyclo [2.2.1]庚烷,具有(1 S,3 S,4 R,6 S)或(1 R,3 R,4 S,6 S)-配置。如电生理研究所示,该化合物可被两性触角感知。
