岩白菜素为碳苷类化合物,具有广泛的生理活性。本文通过一系列反应,将岩白菜素分子中4位羟基的构型由S转化为R,合成得到其非对映异构体4(R)-岩白菜素,为岩白菜素的衍生化研究提供了新的思路。
Bergenin is a carbon glycoside compound with a wide range of physiological activities. In this paper, a series of reactions were carried out to convert the configuration of the 4-hydroxyl group in the bergenin molecule from S to R to derive the diastereomer 4 (R) Provide a new way of thinking.
