摘要
通过四乙酰溴代糖(葡萄糖,半乳糖)与7个不同的取代芳香醇,经过糖苷化,脱乙酰基,以及脱苄基(5e,5f)合成了14个红景天苷及其类似物,并通过~1H NMR和元素分析对其结构进行了表征。新合成化合物在糖供体以及苯环取代基上不同于红景天苷。
About 14 salidrosides and their analogues were prepared by acetobrome-sugars (glucose and galactose) and 7 different substitutes of aromatic alcohol through glucosidation, deacetylation, debenzylation (5e, 5f). Their structures were characterized by ^1H NMR and elemental analysis: The novel compounds differ in the substitutes attached to the benzene ring or in the glycosyl donor.
