该中间体在本合成路线中的序号：(III)The condensation of homogeranyl iodide (III) with diethyl ethoxycarbony-methylphosphonate (IV) by means of NaH in diethoxyethane gives the phosphorane (V), which by a Wittig condensation with 4-methyl-6-acetoxy-4-hexenal (VI) by means of NaH yields 7-(ethoxycarbonyl)-3,11,15-trimethyl-2,6,10,14-hexadecatetraen-1-ol acetate (VII). Finally, this compound is reduced and hydrolyzed by treatment with LiAlH4.
