Base-catalyzed intramolecular nucleophilic substitution for the 2-nitro group in 2-hydroxyanilides of 2-nitrobenzoic acids gave dibenzo[b,f][1,4]oxazepin-11(10H)-ones. In particular, 3-nitrodibenzo[b, f][1,4]oxazepin-11(10H)-one was obtained from N-(2-hydroxyphenyl)-2,4-dinitrobenzamide. The nitro group in the product could also be replaced under the action of O- and S-nucleophiles.
碱催化分子内亲核取代 2-硝基苯甲酸的 2-羟基苯胺中的 2-硝基得到 dibenzo[b,f][1,4]oxazepin-11(10H)-ones。特别是,3-nitrodibenzo[b, f][1,4]oxazepin-11(10H)-one 是从 N-(2-hydroxyphenyl)-2,4-dinitrobenzamide 中获得的。在O-和S-亲核试剂的作用下,产物中的硝基也可以被取代。
