摘要
摘要 开发了一种用于合成以前未知的[1,2,5]噁二唑并[3,4-d][1,2,3]三嗪-7(6H)-酮杂环系统的直接方案。所述方法基于带有芳香族和脂肪族取代基的 (1,2,5-oxadiazolyl)carboxamide 衍生物的串联重氮化/偶氮偶联反应。此外，还对合成的呋喃并[3,4-d][1,2,3]三嗪-7(6H)-酮的 NO 供体能力进行了评估。所阐述的方法提供了获得新型氮杂环化合物的途径，这些化合物具有作为候选药物或功能有机材料恒温组分的潜在应用价值。Chem.2024, 20, 2342–2348. doi:10.3762/bjoc.20.200
Tandem diazotization/cyclization approach for the synthesis of a fused 1,2,3-triazinone-furazan/furoxan heterocyclic system
Abstract
A straightforward protocol for the synthesis of a previously unknown [1,2,5]oxadiazolo[3,4-d][1,2,3]triazin-7(6H)-one heterocyclic system was developed. The described approach is based on tandem diazotization/azo coupling reactions of (1,2,5-oxadiazolyl)carboxamide derivatives bearing both aromatic and aliphatic substituents. The NO-donor ability of the synthesized furoxano[3,4-d][1,2,3]triazin-7(6H)-ones was additionally evaluated. The elaborated method provides access to novel nitrogen heterocyclic compounds with potential applications as drug candidates or thermostable components of functional organic materials.
