Rezumat:

The paper presents the 7 step preparation of (2,3,4-tri-O-benzyl-β-D-glucopyranosyl) phenyl sulfone and (3-O-benzyl-4,6-benzilidene-β-D-glucopyranosyl) phenyl sulfone starting from the same starting material.The key step is the benzylation in PTC conditions of 4,6-benzylidene-1-thio-β-D-glucopiranoside which furnish both precursors for two phenyl sulphone synthesis. For the target compounds the 13C-NMR data are also presented.
