Abstract
Clickable unnatural sugars have been widely used in studying glycosylation in living systems via the metabolic glycan labelling (MGL) strategy. Partial protection of unnatural sugars by 1,6-di-O-acylation increases the labelling efficiency while avoiding the non-specific S-glyco-modification. Herein, we report the facile synthesis of a series of clickable unnatural sugars in both the unprotected and 1,6-di-O-acylated forms at the ten-gram scale. By evaluation of the labelling specificity, efficiency, and biocompatibility of various 1,6-di-O-acylated sugars for MGL in cell lines and living mice, we demonstrate that 1,6-di-O-propionylated unnatural sugars are optimal chemical reporters for glycan labelling. The synthetic routes developed in this work should facilitate the widespread use of MGL with no artificial S-glyco-modification for investigating the functional roles of glycans.
