1,5,5,9-Tetramethyl-2-decalone (6) was synthesized from 5,5,9-trimethyl-1-decalone (7) and irradiated in n-hexane under a nitrogen atmosphere using a high pressure mercury lamp. Oxygen was passed through the reaction mixture in the dark to give a seco-nor acid, 1-carboxymethyl-2-ethyl-2,6,6-trimethylcyclohexane (8a) and a seco acid, 1-(2-carboxyethyl)-2-ethyl-2,6,6-trimethylcyclohexane (9a).
1,5,5,9-四甲基-2-癸酮(6)由5,5,9-三甲基-1-癸酮(7)合成,并在氮气环境下使用高压汞灯照射正己烷。在黑暗中通入氧气,得到仲酸1-羧甲基-2-乙基-2,6,6-三甲基环己烷(8a)和仲酸1-(2-羧乙基)-2-乙基-2,6,6-三甲基环己烷(9a)。
