  A New Intramolecular Migration in Thiosugar Chemistry: S → O Transfer of a Benzothiazol-2-Yl Group in Saccharidic Sulfones

  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.
