A new efficient pre-activation method for the highly alpha-stereoselective glycosylation of 2-deoxysugars and 2,6-dideoxysugars has been developed using 2-deoxy- and 2,6-dideoxythioglycosides as glycosyl donors. The approach allows a wide range of glycosyl acceptors and donors to be used; the alpha-selectivity is very good to excellent.
使用2-脱氧和2,6-二脱氧
硫代糖苷作为糖基供体,已经开发出一种用于2-脱氧糖和2,6-二脱氧糖的高度α-立体选择性糖基化的新的有效预活化方法。该方法允许使用广泛的糖基受体和供体。alpha选择性非常好,甚至非常好。
