The direct coupling of the pyridyl sulfone of N-acetylglucosamine with aldehydes or ketones is promoted by samarium diiodide affording the corresponding α-C-glycosides preferentially. A C-disaccharide has been synthesized using this approach.
C-glycosylation - samarium diiodide - pyridyl sulfones - anomeric anions - N-acetyl glucosamine
