Copper-mediated aerobic oxidative synthesis of benzimidazo fused quinazolines via a multicomponent approach

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

Synthesis of benzimidazo[1,2-c]quinazolines as possible bronchodilators

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-(
