Step by step: A streamlined practical iterative synthesis of S-oligosaccharides is developed in aqueous solution without the need of protecting any of the hydroxy groups. Various deoxythio sugar building blocks can be prepared efficiently. The Ca(OH)2-promoted aqueous S-glycosylation can be realized with high chemo- and stereoselectivity.

A mutant α-xylosidase that lacks its catalytic acid/base residue efficiently catalyses the synthesis of O-linked isoprimeverosides (Xyl-α-1,6GlcOR) in near quantitative yields.

For the first time, the thioglycoligase strategy has been successfully applied to alpha-glycosidases. The alpha-thioglycoligases derived from the family 31 glycosidases, alpha-xylosidase from E. coli (YicI) and alpha-glucosidase from Sulfolobus solfataricus, catalyze thioglycoligase reactions using alpha-glycosyl fluorides and deoxythioglycosides as donors and acceptors, respectively, in yields up

This work highlights the synthesis of glycosyl luciferins and their potential for determining glycosidase activity. Two novel synthetic routes were developed that were used to introduce the luciferin moiety in a late-stage of the sequence and the linear range of the glycosidase assays and kinetics of the substrates were determined.
