A variety of benzimidazo[1,2-c]quinazolin-6-ones derivatives can be accessed in moderate to good yields under simple and metal-free reaction conditions using indoles and o-benzenediamines oxidized by iodine and TBHP. This procedure works in reasonable yields for different indoles as well as o-benzenediamines thus may provide a good synthesis of quinazolinones. A TBHP oxidized ring expansion reaction mechanism that explains the synthesis of benzimidazo[1,2-c]quinazolin-6-ones were reported.

I 2 / TBHP氧化吲哚和苯二胺的无金属合成苯并咪唑[1,2 - c ]喹唑啉-6-酮

使用吲哚和被碘和TBHP氧化的苯二胺,可以在简单且无金属的反应条件下,以中等到良好的产率获得各种苯并咪唑并[1,2 - c ]喹唑啉-6-酮衍生物。对于不同的吲哚以及苯二胺,该方法均以合理的产率进行,因此可以提供喹唑啉酮的良好合成。据报道,TBHP氧化环膨胀反应机理解释了苯并咪唑并[1,2 - c ]喹唑啉-6-的合成。
