In this communication we report a new strategy toward ketopyranosides based on a carbene-mediated activation of the anomeric C-H bond of carbohydrates. By forming a new carbon-carbon bond after a glycosylation step, this approach enables the preparation of both alpha- and beta-ketopyranosides from advanced precursors.
