摘要：

Saccharidic benzothiazol-2yl sulfones - readily obtained through regioselective Mitsunobu thiofunctionalization followed by standard S-oxidation - can easily undergo benzothiazol-2-yl group S --> O transfer when submitted to the action of a hindered base under controlled conditions. An ipso-substitution process is the key-step of this novel intramolecular rearrangement of saccharidic sulfones.
