The sulfoxideglycosylationreaction works remarkably well for many difficult glycosylations. We attribute this in part to the fact that an extremely reactive intermediate can be generated rapidly under mild conditions at low temperature. We find that anomeric sulfenates can be formed in the reaction and that these intermediates impede glycosylation at low temperature. A mechanism for sulfenate formation
