  Piperidinium tetrathiotungstate as sulfur transfer reagent: synthesis of cyclic disulfides

  摘要：

  Piperidinium tetrathiotungstate has been found to react with a number of 1,n-dihalo compounds to afford the corresponding cyclic disulfides in good yields, under mild reaction conditions. This new methodology has been used as a key step in the synthesis of (+/-)-lipoic acid (35) and asparagusic acid (37).
