Rai, Byanju,Kumar, Promod,Kumar, Atul
, p. 85915 - 85918 (2015/11/03)
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
General and efficient copper-catalyzed aerobic oxidative synthesis of N-fused heterocycles using amino acids as the nitrogen source
Liu, Qing,Yang, Haijun,Jiang, Yuyang,Zhao, Yufen,Fu, Hua
, p. 15636 - 15644 (2013/09/12)
A general and 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 heterocycles.
Synthesis of benzimidazo[1,2-c]quinazolines as possible bronchodilators
Rao, A. Raghu Ram,Bahekar, Rajesh H.
, p. 434 - 439 (2007/10/03)
Synthesis of some 6-aryl-benzimidazo[1,2-c]quinazolines 4 have been critically investigated. The first method, based on the condensation of substituted-1,3-benzoxazin-4-(3H)-one 2 with o-phenylenediamine followed by cyclization of the resulting 2-aryl-3-(
