1,6-Diketone, available in eight steps from homocamphorquinone, was converted into 1,5,5,11,11-pentamethyltricyclo2,6>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-pentamethyltricyclo2,6>undec-2-en-4-one by treatment with diphosphorus pentoxide-methanesulfonic acid.
