Using 1,1,6-trimethyl-2-carbethoxy-cyclohexan-3-one as starting material, 6-methyl-γ-cyclogeranic ester, 6-methyl-γ-cyclogeraniol, and 6-methyl-γ-cyclocitral have been synthesized. 6-Methyl-γ-cyclocitral, condensed with acetone, led to a mixture of about equal parts of 6-methyl-γ- and 6-methyl-b̃-ionone (γ- and β-irone). The two ketones have been separated by means of their phenylsemicarbazones.
以1,1,6-三甲基-2-乙氧基-环己烯-3-酮为原料,6-甲基-γ-环香叶酯,6-甲基-γ-环香叶醇和6-甲基-γ-环柠檬酸已经合成。用丙酮缩合的6-甲基-γ-环柠檬酸产生约等份的6-甲基-γ-和6-甲基-β-紫罗兰酮(γ-和β-丙酮)的混合物。两种酮已通过它们的苯基半咔唑分离。
