A novel, efficient, and atom-economical approach for the construction of quinazolinones from 2-nitrobenzaldehydes has been unveiled via copper-catalyzed nitrile formation, hydrolysis, and reduction in onepot for the first time. In this reaction, urea is used as a source of nitrogen for nitrile formation, hydrazine hydrate is used for both the reduction of the nitro group and the hydrolysis of nitrile
首次通过铜催化的腈形成、水解和还原在一个锅中揭示了一种从 2-硝基苯甲醛构建喹唑啉酮的新型、高效和原子经济的方法。在该反应中,尿素用作生成腈的氮源,水合肼用于硝基的还原和腈的水解,大气中的氧气用作唯一的氧化剂。该方法描绘了具有良好官能团耐受性的宽底物范围。此外,该方法还用于合成裂殖菌素、色胺菊酯、phaitanthrin-A、phaitanthrin-B和8 H-喹唑啉[4,3 - b ]quinazolin-8-one。

A versatile and practical “on-water” protocol was newly developed to synthesize quinazolinones using o-bromobenzonitrile as a novel starting material. Studies have found that air as well as water plays an important role in synthesis of quinazolinones. Further investigation indicated that dihydroquinazolinones can be prepared with this protocol under the protection of N2. The protocol can be extended
