  Cycloalkanoindoles. 1. Syntheses and antiinflammatory actions of some acidic tetrahydrocarbazoles, cyclopentindoles, and cycloheptindoles

  摘要：

  A novel series of acidic cycloalkanoindoles comprising tetrahydrocarbazole-, cyclopentindole-, and cycloheptindole-1-acetic acids has been synthesized via the Fischer indolization between a phenylhydrazine and a 1-alkyl-2-oxocycloalkaneacetic acid ester. These compounds were evaluated, orally, for their capacities to decrease estabished adjuvant arthritis in rats. The most active compound of the series was 1-ethyl-8-n-propyl-1,2,3,4-tetrahydrocarbazole-1-acetic acid (AY-24 873),which had an ED50 of 1.1 +/- 0.2 mg/kg. AY-24 873 was also studied orally in rats for its effect on the acute inflammatory response in the carrageenin paw edema test. It was found that AY-24 873 was about ten times more active against the chromic than against the acute models of inflammation used.

  Aspidospermidine 通过分子内级联跨环环化的正式合成

  摘要：

  据报道，通过 Stork 倒数第二个三环酮中间体的新制备方法，正式合成了 aspidospermidine。合成的关键步骤包括分子内级联跨环环化，通过去除 Boc 基团触发，同时形成 aspidospermidine 的 C、D 和 E 环，并通过脱羧烷基化反应方便地建立季立体中心β-酮酯。

  aspidospermidine is reported through a novel preparation of Stork's penultimate tricyclic ketone intermediate. The key steps of the synthesis consist of an intramolecular cascade transannular cyclization, triggered by the removal of Boc group, which simultaneously forms the C, D, and E rings of aspidospermidine and conveniently setting up the quaternary stereo-center via decarboxylative alkylation reaction of the
