Heating a mixture formed by alkali isomerization of methyl linolenoate (1) produces a complex mixture with the bicyclic hexahydroindenoic esters 4β-(7-methoxycarbonylheptyl)-5α-methyl-2,3,3aα,4,5,7aαhexahydroindene (CL5) and 4β-ethyl-5α-(6-methoxycarbonylhexyl)-2,3,3aα,4,5,7aα-hexahydroindene (CL6) as main components. Similar isomerization reactions of three synthetic model compounds, methyl 9Z,13E
加热由亚麻酸甲酯(1)的碱异构化形成的混合物,产生与双环六氢茚基酸酯4β-(7-甲氧羰基庚基)-5α-甲基-2,3,3aα,4,5,7aα六氢茚(CL5)和4β的复杂混合物-乙基-5α-(6-甲氧基羰基己基)-2,3,3aα,4,5,7aα-六氢茚(CL6)为主要成分。三种合成模型化合物的相似异构化反应,分别是9 Z,13 E,15 Z-十八碳三烯酸甲酯(2),9 Z,14 E,16 E-十八碳三烯酸甲酯(4)和9 Z,11 E,15 Z-十八碳三烯酸酯(5)证实了用碱异构化的亚麻酸甲酯获得的结果。
