its derivatives are useful for numerous synthetic transformations in which the anomeric centre of unprotected reducing sugars is selectively activated in aqueous solution. As such unprotected sugars can undergo anomeric substitution with a range of added nucleophiles, providing highly efficient routes to a range of glycosides and glycoconjugates without the need for traditional protectinggroup manipulations

The conversion of sugars into glycomimetics typically involves multiple protecting‐group manipulations. The development of methodology allowing the direct aqueous conversion of free sugars into glycosides, and mimics of oligosaccharides and glycoconjugates in a high‐yielding and stereoselective process is highly desirable. The combined use of 2‐azido‐1,3‐dimethylimidazolinium hexafluorophosphate and
