An efficient and practical method has been manifested for the diversity-oriented synthesis of quinolines via Friedlander annulation reaction for the generation of a wide range of structurally interesting and pharmacologically significant compounds by using ceric ammonium nitrate as a catalyst (10 mol %) at ambient temperature in 45 min. A variety of functional groups are introduced at various positions of the quinoline moiety, and further the diversity of the core skeleton was expanded at R-1 and R-2 positions by the synthesis of various hybrids. Initial screening of the compounds for cytotoxicity against a series of cancer cell lines showed promising results,

facile and practical approach to the synthesis of a wide range of functionalized quinolines was developed via a tandem heteroannulation reaction of o-aminoarylketones with diverse α-methylene ketones in high yields by using tetrabutylammonium peroxydisulfate as a versatile reagent (25 mol%) at ambient temperature under solvent-free conditions. This protocol was applied to the synthesis of drug-like molecules
