  Versatile Synthetic Approaches Towards Aza-analogues of Illudin and Ptaquilosin Sesquiterpenes

  摘要：

  通过手性吡咯烷硝基与双环亚丙基或亚甲基丙基丙烷的 1,3-二极环加成反应，以及加成物的热重排，合成了具有δ-螺环丙烷基团的吲哚嗪酮类化合物，它们是强致癌倍半萜类化合物哌喹罗苷和伊柳丁的杂环类似骨架。它们在 pUC18 DNA 质粒上具有适度的 DNA 裂解活性，为了解这类化合物的结构-活性关系提供了有用的线索。

  Studies on the Synthesis of Aza Analogues of Illudins by Cycloadditions to Highly Strained Methylenecyclopropanes

  摘要：

  A series of 3-spirocyclopropane-tetrahydropyrid-4-ones has been synthesized by the method consisting of nitrone cycloaddition to bicyclopropylidene and thermal rearrangement of the adducts. Regioisomeric 5-spirocyclopropanetetrahydropyrid-4-ones and 5-spirocyclopropanedihydropyrid-4 ones were instead obtained by cycloaddition of nitrones and nitrile oxides, respectively, to methylenespiropentane, followed by thermal rearrangement. Methylenedispiro[2.0.2.1]heptane gave, in turn, 5,6-bis(spirocyclopropane)dihydropyrid-4 The new compounds were prepared as simple aza analogues of the cytotoxic natural products illudins and ptaquiloside in order to study their activity in cleaving a DNA plasmid. The activities shown by several of the compounds are moderate, but from a comparative qualitative analysis of the results a useful structure-activity relationship for this new class of compounds could be derived.

  A series of 3-spirocyclopropanedihydro- and -tetrahydropyrid-4-ones have been synthesized by nitrone cycloaddition to 1,1′-bicyclopropylidene (BCP), chemoselective reduction of the N–O bond of the isoxazolidine ring, and PdII-catalyzed cascade rearrangement of the β-aminocyclopropanol derivatives into the final products. The new tetrahydropyridone derivatives were also prepared by thermal rearrangement
