this report we describe the synthesis of spirocyclic pyridoazepines starting from easily available precursors. The key step of our synthesis is an intramolecular nucleophilic aromatic substitution of the appropriate 3-substituted 2-chloropyridines. The final compounds, designed as simplified analogues of the alkaloid galanthamine, showed significant acetylcholinesterase inhibition activity.(© Wiley-VCH
在本报告中,我们描述了从容易获得的前体开始合成螺环吡啶并氮杂。我们合成的关键步骤是适当的 3-取代 2-氯吡啶的分子内亲核芳香取代。最终化合物设计为生物碱加兰他敏的简化类似物,显示出显着的乙酰胆碱酯酶抑制活性。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
