Due to their high stability, N-glycosyl amides have so far not been considered as glycosyl donors for glycosylation reactions. Two new procedures for the cleavage of the anomeric amide functionality under mild reaction conditions and further stereoselective in situ conversions of the activated glycosyl donors with alcohols and amines to give β-configured O- and N-glycosides are described in this article
由于它们的高稳定性,N-糖基酰胺迄今为止还没有被认为是糖基化反应的糖基供体。本文描述了在温和反应条件下裂解异头酰胺官能团的两种新程序,以及活化糖基供体与醇和胺的进一步立体选择性原位转化以产生 β-构型的 O-和 N-糖苷。
