The freshwater diatom Asterionella formosa (Bacillariophyceae) produces octa-1,3E,5Z-triene (6) (fucoserratene), previously identified as the sexual pheromone of the brown seaweed Fucus serratus. Fucoserratene is biosynthesised from eicosa-5,8,11,14,17-pentaenoic acid (7) by oxidative cleavage of the corresponding 12-hydroperoxy intermediate 8. The biosynthetic sequence was established using eicosa-5
淡水硅藻星杆台塑(硅藻)产生辛-1,3- ê,5 ž -三烯(6)(fucoserratene),预先确定为褐海藻的性信息素墨角藻锯。Fucoserratene是由Eicosa-5,8,11,14,17-戊烯酸(7)通过相应12-氢过氧中间体8的氧化裂解而生物合成的。使用eicosa-5,8,11,14-tetraen-17-ynoic acid(18)建立生物合成序列,eicosa-5,8,11,14-tetraen-17-ynoic acid(18)是7的结构类似物,将其转化为octa-1,3 E -dien-5-yne(21),结构类似物为6,由福寿菌的匀浆物组成。另外,描述了从花生四烯酸制备高度不饱和类花生酸的一般方法。
