  Arene cis-dihydrodiols—useful precursors for the preparation of antimetabolites of the shikimic acid pathway: application to the synthesis of 6,6-difluoroshikimic acid and (6S)-6-fluoroshikimic acid

  摘要：

  The synthesis of 6,6-difluoroshikimic acid (11) has been achieved in ten steps from the enantiopure diol 16, which is derived from enzymatic cis-dihydroxylation of iodobenzene. The versatility of the synthetic strategy has been demonstrated by the preparation of the known antimicrobial agent, (6S)-6-fluoroshikimic acid (5). (c) 2006 Elsevier Ltd. All rights reserved.

  Difluorinated analogues of shikimic acid

  摘要：

  Investigations into the quinate to shikimate transformation have been carried out, the results of which have been exploited in the synthesis of a novel difluoromethylene homologue of shikimic acid from (-)-quinic acid. Martin's sulfurane {Ph2S[OC(CF3)(2)Ph](2)} was the reagent of choice for the key dehydration step of this synthesis. The results of investigations into the synthesis of the important natural product analogue, 6,6-difluoroshikimic acid are also reported. (C) 2003 Elsevier Science Ltd. All rights reserved.

  The synthesis of 6.6-difluoroshikimic acid (4) has been achieved in nine Steps from the enantiopure diol 9, which is derived from microbial dihydroxylation of iodobenzene. The synthetic strategy has also been demonstrated to be applicable to the preparation of other 6-substituted anologues of shikimic acid. (C) 2004 Elsevier Ltd. All rights reserved.
