  Efficient Synthesis of the Tetracyclic Aminoquinone Moiety of Marmycin A

  摘要：

  An efficient four-step route to the tetracyclic aminoquinone moiety of marmycin A that proceeds in 41% overall yield from 5-nitronaphthoquinone and 5-methyl-1-vinylcyclohexene will facilitate preparation of marmycin A analogues for biological evaluation. The Diels-Alder reaction gave exclusively the desired adduct that is favored by steric considerations rather than the regioisomeric adduct that is favored by electronic considerations.

  Mar霉素A的合成研究：C3'-去甲基类似物的制备

  摘要：

  研究了天然产物mar霉素A的全合成。以脱羧烷基化，Pd（OAc）2催化的环化，芳构化和CN偶联为关键步骤，建立了关键片段8-氨基-3-甲基苯并[ a ]蒽醌（1）的快速合成策略。然而，由于无法获得碳水化合物片段2，mar霉素A的最终组装受阻。取而代之的是，使用InBr 3催化的C-和N以适度的产率制备了一个小霉素霉素A的去甲基类似物文库-糖基化反应。这些化合物的绝对构型通过将其光谱数据与with霉素A的光谱数据进行比较，并通过X射线分析得以证实。

• InBr₃-Catalyzed Glycosidation of Glycals with Arylamines: An Alternative Approach To Access 4-Aminocyclopent-2-enones

  日期：2011.4.15

  To turn side products into major products, a novel strategy to access biologically active 4-aminocyclopent-2-enones was developed. These compounds were originally identified as side products but became major products when 3,5-dimethylpyran-3,4-diol 7a was used as the substrate and 30% InBr3 as the catalyst. Aryl- or heteroarylamines as well as variously substituted glycals can be used in this reaction, and the corresponding 4-aminocyclopent-2-enones were obtained in moderate to good yields. These compounds can be further used to prepare 4-aminocarbocyclic nucleosides.
