(6Z,9Z,12Z)-6,9,12-Octadecatriene and (3Z,6Z,9Z,12Z)-3,6,9,12-icosatetraene, hydrocarbons unsaturated more highly than usual lepidopteran Type II pheromones, were identified from geometrid females of Hemithea tritonaria and Thalassodes immissaria intaminata, respectively. The triene was synthesized by a double Wittig reaction between hexanal and an ylide derived from (Z)-1,6-diiodo-3-hexene, and the tetraene was synthesized by a coupling between (Z)-3-undecenal and an ylide derived from (3Z,6Z)-1-iodo-3,6-nonadiene. Each synthetic compound attracted males of the corresponding emerald moths in a field. (C) 2009 Elsevier Ltd. All rights reserved.
根据 (6Z,9Z,12Z)-6,9,12-十八碳三烯和 (3Z,6Z,9Z,12Z)-3,6,9,12-二十碳四烯,这两种烃类化合物比通常的鳞翅目昆虫II型性外激素具有更高的不饱和度,分别从橘斑斜纹夜蛾(Hemithea tritonaria)和黑边绿舟蛾(Thalassodes immissaria intaminata)的雌蛾中鉴定出来。三烯通过己醛与由 (Z)-1,6-二碘-3-己烯衍生的亚胺基进行双 Wittig 反应合成,而四烯则通过 (Z)-3-十一醛与由 (3Z,6Z)-1-碘-3,6-壬二烯衍生的亚胺基进行偶联反应合成。每种合成的化合物都能在田间吸引相应绿舟蛾的雄蛾。(C) 2009 Elsevier Ltd. 保留所有权利。
