An efficient method for the synthesis of quinolines using microwave irradiation was developed providing 28 quinolines with good yields. The reaction procedures are environmentally friendly, convenient, mild and of easy work-up. Quinolines were evaluated for their antifungal, anticancer and antioxidant properties and exhibited high activities in all tests performed.

efficient method has been developed for the synthesis of quinolines by Yb(OTf)3 catalyzed three-component reaction of aldehydes, alkynes, and amines undermicrowaveirradiation in ionic liquid. A series of 2,4-disubstituted quinolines was synthesized in excellent yield (69-93%) under mild reaction condition and the catalyst was recycled for four cycles. microwave assisted - ytterbium triflate - one-pot

Microwave-assisted one-pot three-component reaction between aromatic amines, aromaticaldehydes and phenylacetylene is accomplished efficiently in the presence of catalytic amounts of potassium dodecatungstocobaltate trihydrate (K5CoW12O40·3H2O) to afford the corresponding quinolines and bis-quinolines in excellent yields. Selective conversion of aromaticaldehyde and also arylacetylene to their corresponding

the iron-catalyzed oxidative cyclization of alcohol/methyl arene with 2-amino styrene to synthesize polysubstituted quinoline. Low-oxidation level substrates such as alcohols and methyl arenes are converted to aldehydes in the presence of an iron catalyst and di-t-butyl peroxide. Then, the quinoline scaffold is synthesized through imine condensation/radical cyclization/oxidative aromatization. Our
