Reactions of tetracyanoethylene with N′-arylbenzamidines: A route to 2-phenyl-3 H -imidazo[4,5- b ]quinoline-9-carbonitriles
(2013)Eight 2-phenyl-3H-imidazo[4,5-b]quinoline-9-carbonitriles 15 are prepared in four steps from N′-arylbenzamidines 11 and tetracyanoethylene (TCNE) in ∼70-90% yields. The transformation involves the initial formation of ...
