以天然的咖啡酸、甘草次酸和齐墩果酸为原料, 采用侧基保护、还原、酰化与去保护等步骤, 将咖啡酰基及氢化咖啡酰基引入到甘草次酸和齐墩果酸的3-位羟基上, 以较高收率合成了4 个新的咖啡酸及氢化咖啡酸五环三萜酯类化合物, 通过IR, 1H NMR, HRMS 等方法确定了化合物的结构.

Four new caffeyl triterpenic esters were synthesized from natural caffeic acid, glycyrrhetinic acid and oleanolic acid. The structures of all products were characterized by IR, 1H NMR and HRMS techniques. The activities of the compounds to protect liver was tested and compound 9c showed good hepatic protective effect.

Key words: caffeyl glycyrrhetinate, caffeyl oleanolic ester, synthesis, hepatic protection
