A new direct route to the stereospecific construction of a glycosides and a disaccharides of ulosonic acids is presented. Addition reaction of alcohols and/or "sugar alcohols" to the quaternary double bond of sugar ketene dithioacetal 1 mediated by trimethylsilyl triflate led to the corresponding O-glycosides. Subsequent hydrolysis of dithianyl residue afforded the title compounds.
