Carbohydrate Chemistry and Glycobiology have witnessed a rapid expansion during the last few years with the development of numerous new, imaginative and efficient syntheses which provide further insight into structures and biological interactions of glycoconjugates. Glycosylation reactions are widel

A new approach towards the synthesis of glycosides based upon a (formal) insertion of glycosylidene carbenes into 0-H bonds is presented. The synthesis and characterization of the glycosylidene-derived diazirines 25-28, precursors of glycosylidene carbenes, are described. The diazirines were prepare
