THE SYNTHESIS OF 3-O-[(BENZYLTHIO)CARBONYL]-β-D-GLUCOPYRANOSE AND METHYL 2,4,6-TRI-O-BENZOYL-α AND β-D-GLUCOPYRANOSIDES

Abstract
The discovery that the (benzylthio)carbonyl group is stable in concentrated hydrochloric acid has permitted the removal in that medium of isopropylidene blocking groups from 3-O-[(benzylthio)carbonyl]-1,2;5,6-di-O-isopropylidene-α-D-glucofuranose to furnish crystalline 3-O-[(benzylthio)carbonyl]-β-D-glucopyranose. Benzoylation of the latter provided a derivative which has made possible the synthesis of methyl 2,4,6-tri-O-benzoyl-α and β-D-glucopyranosides.
