Metal-catalyzed Stereoselective and Protecting-group-free Synthesis of 1,2-<i>cis</i>-Glycosides Using 4,6-Dimethoxy-1,3,5-triazin-2-yl Glycosides as Glycosyl Donors
4,6-Dimethoxy-1,3,5-triazin-2-yl glycosides, glycosyl donors prepared in one step from free saccharides without protection of the hydroxy groups, were stereoselectively and equivalently converted t...
key step for the synthesis of sugar-containing molecules such as glycolipids. However, traditional carbohydrate chemistry is characterized by extensive use of protective groups, resulting in laborious manipulations and poor atom economy. Here, we present a protecting-group-free glycosylation strategy employing dibenzyloxy-1,3,5-triazin-2-yl glycosides (DBT-glycosides) as glycosyl donors. The DBT-glycosyl

The reaction of sugars with alcohols and catalytic amounts of an acid in a high frequency field (2.45 GHz) leads to high yields of the corresponding alkyl glycosides. The ratio of the alpha/beta -anomers is influenced by the reaction conditions and reaction controlling.
