Abstract

[figure: see text] 1,2-Migration and concurrent glycosidation of phenyl 2,3-O-thionocarbonyl-1-thlo-alpha-L-rhamnopyranosides under the action of methyl trifluoromethanesulfonate (MeOTf) afforded in high yields the 3-O-(methylthio)carbonyl-2-S-phenyl-2,6-dideoxy-beta-L-glucopyranosides, ready precursors to the corresponding 2-deoxy-beta-glycosides.
