cyclobutanoid monoterpene alcohol (maconelliol) that together with lavandulyl 2-methylbutanoate constitutes the sex pheromone to attract males from a distance. Enantioselective syntheses of four different stereoisomers of the major component, maconelliyl 2-methylbutanoate 1, from alpha-pinene are reported. Absolute configurations of both naturally occurring maconelliyl 2-methylbutanoate 1 and the minor component
粉色芙蓉粉虱(Maconellicoccus hirsutus,绿色)是一种外来害虫,最近入侵南加州和佛罗里达州。雌性hirsutus释放一种新型的环丁烷单萜醇(马可奈醇)的2-甲基丁酸,它与2-甲基丁酸的lavandulyl一起构成性信息素,以吸引远距离的雄性。据报道,来自α-pine烯的主要成分的四种不同立体异构体的对映异构体合成是1,2-甲基丁酸Macellelliyl 2-methylbutanoate。已经建立了天然存在的2-甲基丁酸马来烯基酯1和次要成分2-甲基丁酸lavandulyl 2的绝对构型。
