【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。更多还原

【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.更多还原
