Synthetic studies aimed at the elucidation of the stereostructure of the aggregation pheromone, 2-methyl-6-(4′-methylenebicyclo[3.1.0]hexyl)hept-2-en-1-ol, produced by the male stink bug Erysarcoris lewisi

The male-produced aggregation pheromone of the stink bug Erysarcoris lewisi Distant was shown to be one of the two diastereomers of (2Z,6R)-2-methyl-6-(4′-methylenebicyclo[3.1.0]hexyl)hept-2-en-1-ol by synthesizing and bioassaying (2E,6R)-, (2E,6S)-, (2Z,6R)-, and (2Z,6S)-isomers. These were synthesized from the enantiomers of citronellal by employing an intramolecular α-ketocarbene addition to a double
臭臭虫Erysarcoris lewisi Distant的雄性产生的聚集信息素被证明是(2 Z,6 R)-2-甲基-6-(4'-亚甲基双环[3.1.0]己基)庚烷的两个非对映异构体之一通过合成和生物测定(2 E,6 R)-,(2 E,6 S)-,(2 Z,6 R)-和(2 Z,6 S)-异构体来生成-2-en-1-ol 。这些是由香茅醛的对映异构体合成的,方法是将分子内的α-酮卡宾加成双键,并使用E-选择性或Z甲酰基的选择性烯烃化是关键步骤。开发了一种可靠的方法来制备2-(二-邻甲苯基膦酰基膦酸酯)丙酸乙酯,这是Ando的Z选择性烯化试剂。
