✦ Synopsis

Stereospecific Synthesis of α-Glycosides and α-Disaccharides of Ulosonic Acids via Direct Addition of Alcohols to Sugar Ketene Dithioacetal.

-A new direct route to the stereospecific construction of α-glycosides [cf. (V), (XI)] and α-disaccharides [cf. (VIII)] of ulosonic acids via TmsOTf-mediated addition of corresponding alcohols to the quaternary double bond of sugar ketene dithioacetal (I) is presented. -(MLYNARSKI,
