去氢枞酸醇类香料酯的合成与表征

Synthesis and Characterization of Dehydroabietic Acid-alcohol Spice Esters

  • 摘要: 以去氢枞酸为原料,经去氢枞酸酰氯与醇类香料的O-酰化反应,合成得到去氢枞酸肉桂酯、去氢枞酸葑醇酯、去氢枞酸龙脑酯和去氢枞酸薄荷酯等4种去氢枞酸醇类香料酯,其中去氢枞酸肉桂酯和去氢枞酸葑醇酯为新化合物。目标产物的适宜合成条件为:反应时间10 h,反应温度95~100 ℃,反应物n(醇):n(酰氯)=1.2:1。采用IR、UV、NMR和MS等方法对目标产物进行了结构表征。

     

    Abstract: Four types of dehydroabietic acid-alcohol spice esters, i.e. dehydroabietic acid-cinamic alcohol ester, dehydroabietic acid-fenchol ester, dehydroabietic acid-borneol ester and dehydroabietic acid-menthol ester, were synthesized by O-acylation reaction of dehydroabietyl acyl chloride and alcohol spices using dehydroabietic acid as starting material. Suitable synthetic conditions of the target products were found to be as follows: reaction time 10 h, reaction temperature 95-100 ℃, molar ratio of reactants 1.2:1 (alcohol:chloride). The target products were characterized by means of IR, UV, NMR, and MS.
