efficient copper-catalyzed aerobic oxidative method for the synthesis of N-fused heterocycles has been developed by using readily available α-amino acids as the nitrogen source. The reactions underwent N-arylation, aerobic oxidative dehydrogenation, intramolecular cyclization and dissociation of formic acid. This method should provide a general and practical strategy for the construction of N-fused

The first copper mediated aerobic oxidative multi-component synthesis of benzimidazo[1,2-c]quinazolines has been developed from 2-(2-halophenyl)benzoimidazoles, aldehydes and sodium azide as a nitrogen source. This protocol involves the formation of three C–N bonds starting from azidation of haloaryl with sodium azide followed by in situ conversion of azide into arylamine, which on condensation with
苯并咪唑并[1,2- c ]喹唑啉的第一个铜介导的好氧氧化多组分合成是由2-(2-卤代苯基)苯并咪唑,醛和叠氮化钠作为氮源开发的。该方案包括从卤代芳基与叠氮化钠的叠氮化开始,然后将叠氮化物原位转化为芳基胺,形成三个C–N键,然后在与苯甲醛缩合后进行氧化环化,从而得到苯并咪唑[1,2- c ]喹唑啉达到极佳的产量。
