Indolizidinones with a α-spirocyclopropane group, obtained by 1,3-dipolar cycloaddition of chiral pyrroline nitrones to bicyclopropylidene, or methylenespiropentane, and thermal rearrangement of the adducts, have been synthesized as aza-analogous skeleton to the potent carcinogenic sesquiterpenes ptaquiloside and illudin. Their moderate DNA cleaving activity on a pUC18 DNA plasmid furnishes useful hints about structure-activity relationships for this class of compounds.
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。
