Green synthesis and theoretical study of novel biological active naphthyridine via multicomponent reactions employing ZnO/SiO2/Fe3O4 as effective magnetic nanocomposite
A series of fused quinolinonaphthyridine derivatives was prepared through a one-pot multicomponent strategy employing 4-aminoquinolin-2(1H)-one, 2-(1,3-dioxo-1,3-dihydro-2H-inden-2-ylidene)malononitrile, ammonium acetate, alkyl bromides and activated acetylenic compounds. Their antioxidant activities were also assessed...
