Silver Zeolite as Promoter in Glycoside Synthesis. The Synthesis of 2-Deoxy-β-D-Glycopyranosides

Abstract
The use of silver zeolite as a promoter for the preparation of .beta.-linked 2-deoxyglycosides and disaccharides of biological relevance has been explored. Starting from benzoylated glycosyl bromides, the total yield of glycosides varies from 54 to 84% and the .alpha.:.beta. ratio from 0.25 to 1.18.
