中文摘要：
以α-异佛尔酮为原料,在氯化锌和己二酸存在下,尝试合成氧代二氢大马酮香料,却意外得到了氧代二氢大马酮的一个异构体,即标题化合物,用气相色谱-质谱和核磁共振谱进行了结构表征,并研究优化了合成此化合物的工艺条件,即使用无水氯化锌、最佳反应温度为145℃、最佳反应时间为8h。
英文摘要：
One isomer of oxodihydrodamascenone,1-（5,5-dimethylcyclohex-2-ene-1-one-3-yl）-pentan-2-one,was unexpectedly prepared from,α-isophorone in the presence of hexanedioic acid and zinc chloride.The structure of the synthetic perfume compound 2 was identified by GC/MS,1HNMR,and 13CNMR.The conditions for synthesis of the target compound were also optimized using anhydrous zinc chloride at a reaction temperature of 145 ℃ and a reaction time of 8 h,and should be controlled during the refluxing process.
