Access to privileged heterocyclic scaffolds involving 4-aryl-6-(1H-indol-3-yl)-2,2-bipyridine-5-carbonitriles and 6-(2-furyl)-2-(1H-indol-3-yl)-4-arylpyridine-3-carbonitriles frameworks has been achieved via a single-step multicomponent reaction of structurally diverse aldehydes, 2-acetylpyridine (or) 2-acetylfuran and 3-cyanoacetyl indole in ammonium acetate under neat condition. Also a series of
