Reactions of 4- and 4′-substituted chalcones with naphthalen-2-amine afforded isomeric benzo[g]- and benzo[f]quinoline derivatives. Depending on the substituent in the initial chalcone, the cyclization follows two pathways through different intermediates. The product structure was confirmed by IR, 1H and 13C NMR, and massspectra and X-ray analysis.

AbstractThe three-component reactions of aromaticaldehydes, naphthalen-2-amine, and phenylacetylene catalyzed by AgOTf in toluene selectively gave 1,3-diarylbenzo[f]quinolines in high yields. This procedure provides an efficient method for the synthesis of benzo[f]quinolines under mild reaction conditions and with high yields, high selectivity, and operational simplicity.

The three‐component reaction of aromaticaldehyde, naphthalen‐2‐amine and 2‐halogenated acetophenone in THF catalyzed by 5 mol % iodine at reflux unexpectedly gave 1,3‐diarylbenzo[f]quinolines, with halogen losing in the formation of the products. The formation of unexpected 1,3‐diarylbenzo[f]quinolines was tentatively explained by Cram's rule to one of the steps in the mechanism. J. Heterocyclic Chem
芳香醛,萘-2-胺和2-卤代苯乙酮在THF中由5 mol%碘在回流条件下进行三组分反应,出乎意料地产生了1,3-二芳基苯并[ f ]喹啉,在形成产物时卤素损失。克莱姆法则初步解释了意外的1,3-二芳基苯并[ f ]喹啉的形成是该机理的其中一个步骤。J.杂环化学,(2009)。
