Several α,ω-bifunctional derivatives of E,E,E-geranylgeraniol were prepared via convergent synthesis starting with geraniol (8), which was converted in three steps into the tetrahydropyranyl ether of 8-chlorogeraniol (9) and 8-hydroxygeranylphenylsulfone (10). Combination of synthons 9 and 10 with subsequent reductive removal of the phenylsulfonyl group produced the tetrahydropyranyl ether of ω-hydroxygeranylgeraniol (5), hydrolysis of which gave exclusively trans-ω-hydroxygeranylgeraniol (1). Derivatives 5–7 of geranylgeraniol were synthesized using standard methods.
以香叶醇(8)为起始原料,通过收敛合成法制备了E,E,E-香叶基香叶醇的几种α,ω-双官能衍生物,香叶醇(8)通过三个步骤转化为8-氯香叶醇(9)和8-羟基香叶基苯基砜(10)的四氢吡喃基醚。将合成单元9和10组合,随后还原去除苯基砜基,得到ω-羟基香叶基香叶醇(5)的四氢吡喃基醚,水解后得到纯反式-ω-羟基香叶基香叶醇(1)。香叶基香叶醇的衍生物5-7采用标准方法合成。
