Synthesis of 4-methyl-2,3-disubstituted quinoline scaffolds via environmentally benign Fe(III) catalysed sequential condensation, cyclization and aromatization of 1,3-diketone and 2-ethynylaniline

Environmentally benign Fe(III)-catalysed sequential condensation, cyclization and aromatization of 1,3-diketone and 2-ethynylaniline derivatives to the substituted quinoline scaffolds with good to excellent yield in shorter reaction time is described.
