  Tubulin-binding dibenz[c,e]oxepines: Part 2. Structural variation and biological evaluation as tumour vasculature disrupting agents

  摘要：

  5,7-Dihydro-3,9,10,11-tetramethoxybenz[c,e]oxepin-4-ol 1, prepared from a dibenzyl ether precursor via Pd-catalysed intramolecular direct arylation, possesses broad-spectrum in vitro cytotoxicity towards various tumour cell lines, and induces vascular shutdown, necrosis and growth delay in tumour xenografts in mice at sub-toxic doses. The biological properties of 1 and related compounds can be attributed to their ability to inhibit microtubule assembly at the micromolar level, by binding reversibly to the same site of the tubulin alpha beta-heterodimer as colchicine 2 and the allocolchinol, N-acetylcolchinol 4.

  reported. This synthesis represents the most efficient and shortest route to date, featuring three catalytic processes: CuI‐catalyzed redox‐A3 reaction, Pd‐catalyzed reductive carbocyclization, and PtO2‐catalyzed hydrogenation. Importantly, this new strategy to the tetracyclic framework has also been applied to the collective concise syntheses of >30 natural protoberberines (without 13‐methyl group) and

  报告了一种简洁，催化和通用的策略，该策略允许在四个步骤中为每个分子高效地合成22种天然13-甲基原小ber碱。该合成代表了迄今为止最有效，最短的路线，具有三个催化过程：CuI催化的氧化还原A 3反应，Pd催化的还原碳环化和PtO 2催化的氢化。重要的是，这种针对四环框架的新策略也已应用于30多种天然原小ber碱（无13-甲基）和5种金刚烷烷生物碱的集体简明合成中。
