摘　　要：为开发新型紫罗兰类香料,以β-紫罗兰酮为原料,经过NaBH4还原为β-紫罗兰醇后,通过1-乙基-(3-二甲基氨基丙基)碳酰二亚胺盐酸盐(EDC?HCl)/4-二甲氨基吡啶(DMAP)偶合法,研究了β-紫罗兰醇与7种不同的羧酸酯化反应,得到了7种鲜见报道的β-紫罗兰醇酯,产率87.2%～97.2%。并通过1H NMR、^(13)C NMR和高分辨质谱HRMS对目标化合物进行结构表征。同时,对制备的7种酯类物质在水中的香气阈值采用3点选配法(3-AFC)进行测定。结果表明,制备的β-紫罗兰醇酯衍生物的香气阈值在40～300μg/kg之间,高于β-紫罗兰酮的香气阈值0.007μg/kg,且双羧酸β-紫罗兰醇酯的香气阈值要高于单羧酸β-紫罗兰醇酯的香气阈值。In order to develop new fragrance, β-ionol esters were reacted with seven different carboxylic acids by EDH-HC1/DMAP coupling method and reduced by NaBH4 to synthesis seven different β-ionol esters, and the yield for each ester was between 87.2% - 97.2%. The method possessed many advantages such as mild reaction conditions, short reaction time, and easy post-processing. The synthesized compounds were characterized by 1H NMR, L3C NMR and HRMS spectra. At the same time, the aroma threshold value of seven aroma esters was evaluated by 3-AFC test in water. The results showed that the aroma threshold of β-ionol ester derivatives between 40 - 300μg/kg, which is much higher than that of fl-ionone （0.0071xg/kg）, and the aroma threshold of double-carboxylic acid β-ionol ester is higher than that of monocarboxylic acid μ-ionol ester.
