A straightforward and economic method for the synthesis of ferrocene-containing quinolines by the Ce(OTf)3-catalyed one-pot three-component domino cyclization/aromatization reaction of ferrocenylacetylene, aldehydes, and amines under an air atmosphere was developed. A series of ferrocene substituted quinolines have been synthesized from simple and readily available starting materials in good yields
An efficient and greensynthesis of 4-ferrocenylquinoline derivatives through a TsOH-catalyzed three-componentreaction of aromatic aldehydes, amines and ferrocenylacetylene in water has been successfully developed. This strategy is a powerful method for the construction of diverse ferrocenyl-quinoline conjugates from simple available starting materials as it minimized the use of metal catalyst and
