(3S, 13R)-3, 13-Dimethylheptadecane [(3S, 13R)-3, 13-dime-17Hy] is the major pheromone component of the western false hemlock looper (WFHL),Nepytia freemani. In comparative gas chromotographic-electroantennographic detection (GC-EAD) analyses of stereoselectively synthesized isomers, 1 pg of (3S, 13R)-dime-17Hy elicited significantly stronger electrophysiological responses by male WFHL antennae than
(3S, 13R)-3, 13-Dimethylheptadecane [(3S, 13R)-3, 13-dime-17Hy] 是西方假铁杉环虫 (WFHL) Nepytia freemani 的主要信息素成分。在立体选择性合成异构体的比较气相色谱-触角电子检测 (GC-EAD) 分析中,1 pg (3S, 13R)-dime-17Hy 比单独注射的 1 pg (3R, 13R)-dime-17Hy 引起雄性 WFHL 触角明显更强的电生理反应)-, (3R, 13S)- 或 (3S, 13S)-3, 13-dime-17Hy。在使用单独测试的立体异构体的现场实验中。(3S, 13R)-3, 13-dime-17Hy 是唯一吸引雄性的立体异构体,但四种立体异构体混合物的吸引力是其 3.6 倍。(3S, 13R)-3, 13-dime-17Hy 与其他立体异构体的四元和所有二元组合同样具有吸引力,表明
