摘要
目的研究3,5-O-二咖啡酰奎宁酸的合成工艺。方法根据目标化合物3,5-O-二咖啡酰奎宁酸的结构特点,本文选择咖啡酸与奎宁酸作为合成原料,拟采用选择性地保护二者活泼官能团-酰氯成酯-脱保护的方法以得到目标产物。结果目标产物经NMR和MS分析为结构正确的化合物。结论本合成工艺提高了3,5-O-二咖啡酰奎宁酸的产率,但副产物较多,分离较困难。
Objective: To synthesize3,5-O-dicoffeoylquinic acid.Methods:The target compound was obtained after eight steps reaction from Caffeic acid and quinic acid.Results:The structure of synthesized product was confirmed by NMR and MS.Conclusion:Compared wirh other methods,the raw materials is cheaper and the process is more convenier,lower cost,higher yields.
