A novel and expeditious approach to the stereoselective synthesis of 2-S-ethyl(phenyl)-2-deoxy-β-glycosides, ready precursors to 2-deoxy-β-glycosides
摘要:
1,2-Migration and concurrent glycosidation of ethyl(phenyl) 2,3-orthoester-1-thio-alpha-1-rhamnopyranosides under the action of TMSOTf readily afforded the corresponding 2-S-ethyl(phenyl)-2-deoxy-beta-glycosides, ready precursors to 2-deoxy-beta-glycosides.

Abstract 1,2-Migration and concurrent glycosidation of ethyl(phenyl) 2,3-orthoester-1-thio-α- d- and l -mannopyranosides under the action of TMSOTf readily afforded the corresponding 2- S -ethyl(phenyl)-2-thio-β-glucopyranosides, ready precursors to 2-deoxy- arabino -hexopyranosides (2-deoxy-β-glucopyranosides).
