palladium-catalyzed carbonylative procedure for the synthesis of 2-aminobenzoxazinones from 1-azido-2-iodobenzenes and amines has been developed. A broad range of 2-aminobenzoxazinone derivatives were prepared in moderate to excellent yields by using Pd/C as the catalyst under CO atmosphere. Notably, by using organic azides as the substrates, external oxidant usage can be successfully avoided and only forms
已经开发了钯催化的由1-叠氮基-2-碘苯和胺合成2-氨基苯并恶嗪酮的羰基化方法。通过在CO气氛下使用Pd / C作为催化剂,以中等到极好的收率制备了各种各样的2-氨基苯并恶嗪酮衍生物。特别地,通过使用有机叠氮化物作为底物,可以成功地避免外部氧化剂的使用,并且仅形成副产物N 2。
