1,6-Diketone, available in eight steps from homocamphorquinone, was converted into 1,5,5,11,11-pentamethyltricyclo[6.2.1.02,6]undecan-7-one by treatment with potassium t-butoxide and then lithium dimethylcuprate, while α,α-dimethyl-γ-valerolactone, prepared in five steps from homocamphor, was converted into 1,5,5,11,11-pentamethyltricyclo[6.2.1.02,6]undec-2-en-4-one by treatment with diphosphorus
通过用叔丁醇钾和二甲基铜酸锂处理,1,6-二酮可从高樟脑醌八步获得,转化为 1,5,5,11,11-五甲基三环[6.2.1.02,6]undecan-7-one , 而 α,α-二甲基-γ-戊内酯, 由同樟脑分五步制备, 被转化为 1,5,5,11,11-五甲基三环 [6.2.1.02,6]undec-2-en-4-one用五氧化二磷-甲磺酸处理。
