An expedient and facile route for the general synthesis of 3-aryl substituted 1,2,3-triazolo[1,5-a][1,4]benzodiazepin-6-ones and 1,2,3-triazolo[1,5-a][1,5]benzodiazocin-7-ones

We describe herein a convenient approach for the general synthesis of novel tricyclic scaffolds incorporating a fusion of the 1,2,3-triazole ring with difficultly obtainable medium sized rings such as [1,4]benzodiazepin-5-ones and [1,5]benzodiazocin-6-ones through Sonogashira coupling of an aryl iodide with 2-amino-N-methyl-N-(prop-2-ynyl)benzamide or homologue followed by in situ diazotisation, azidation
我们在本文中描述了一种方便的方法,该方法用于一般合成新的三环支架并结合有 1,2,3-三唑 芳基碘与Sonogashira偶合的具有难以获得的中等尺寸环的环,例如[1,4]苯并二氮杂-5-酮和[1,5]苯并二恶唑-6-酮 2-氨基-N-甲基-N-(丙-2-炔基)苯甲酰胺或同系物,然后进行原位重氮化,叠氮化和环加成反应。该策略还允许容易地获得相应的酰胺还原的类似物。操作简单和易于获得的基材使该过程具有成本效益和实用性。
