A novel and expeditious approach to the stereoselective synthesis of 2-S-ethyl(phenyl)-2-deoxy-beta-glycosides, ready precursors to 2-deoxy-beta-glycosides



A novel and expeditious approach to the stereoselective synthesis of 2-S-ethyl(phenyl)-2-deoxy-beta-glycosides, ready precursors to 2-deoxy-beta-glycosides



Tetrahedron Letters 41(16): 2961-2964



1,2-Migration and concurrent glycosidation of ethyl(phenyl) 2,3-orthoester-1-thio-alpha-L-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.
