2-dimethylbutan-3-one, and an undentified compound, which were separated by gas–liquid chromatography. 1-Diethylamino-4-methylpentan-3-one was condensed with 2-methylcyclohexanone to give 2-methyl-2-(4-methyl-3-oxopentyl)cyclohexanone, cyclisation of which in alkali gave 1,1,10-trimethyl-Δ8-2-octalone in small yield.
曼尼希(Mannich)在二甲基异丙基酮上的缩合反应得到1-二乙基氨基-4-甲基戊三-3-酮,1-二乙基氨基-2,2-二甲基丁三-3-酮和一种不明化合物的混合物,通过气-液相色谱法对其进行分离。 。将1-二乙基氨基-4-甲基戊基-3-酮与2-甲基环己酮缩合,得到2-甲基-2-(4-甲基-3-氧戊基)环己酮,将其在碱中环化,得到1,1,10-三甲基- Δ 8 -2- octalone小收率。
