Disclosed is a method for selective synthesis of 1,2-cis-α-linked glycosides which does not require the use of the specialized protecting group patterns normally employed to control diastereoselectivity. Thioglycoside acceptors can be used, permitting iterative oligosaccharide synthesis. The approach eliminates the need for lengthy syntheses of monosaccharides possessing highly specialized and unconventional protecting group patterns.
揭示了一种选择性合成1,2-顺式α-连接的糖苷的方法,该方法不需要通常用于控制对映选择性的专门保护基团模式。可以使用
硫代糖苷受体,从而允许进行
寡糖合成。该方法消除了需要合成具有高度专门化和非常规保护基团模式的
单糖的冗长合成过程。
