  Formal total synthesis of grahamimycin A1

  摘要：

  (S)-t-Butyldimethylsiloxy-2-hexenoic acid and its (R)-isomer were prepared from (S)- and (R)-3-hydroxybutanoic acid esters, respectively. Condensation of the both isomers with 2-(ptoluenesulfonyl)ethyl (4S,5S,7R)-7-hydroxy-4,5-dimethylmethylenedioxyoctanoate, synthesized from methyl 4,6-dideoxy -alpha-D-xylo-hexopyranoside, gave the corresponding esters which were converted into precursors of seco acids of grahamimycin A1 with S or R configuration at the C-6 position (grahamimycin A1 numbering). The (6S)- and (6R)-isomers were respectively subjected to macrolactonization by the use of diethyl azodicarboxylate-triphenylphosphine system or Yamaguchi procedure to afford 11, 12-dihydroxy-grahamimycin A1 whose oxidation to grahamimycin A1 has already been reported.

  An efficient convergent approach to the synthesis of the novel dioxolenone alcohol 3 is described and on thermolysis of 3 a macrodiolide, 12, was obtained via an intermediate β-acyl ketene. Macrodiolide 16 was obtained on thermolysis of the known dioxolenone alcohol 2 rather than the decanolide, diplodialide A.

  本文介绍了一种合成新型二氧戊烯酮醇 3 的高效聚合方法，在热分解 3 的过程中，通过中间体δ-乙酰酮烯获得了大环内酯 12。通过热分解已知的二氧杂环戊烯醇 2 而不是癸内酯--二茂烷基二内酯 A，得到了大环内酯 16。
