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)。

Abstract A mild, efficient, and general method for the synthesis of benzo[f]quinoline derivatives via three-component reaction of arylaldehyde, naphthalen-2-amine, and acetone or acetophenone is described using iodine as catalyst. The features of this procedure are mild reaction conditions, high yields, and operational simplicity.

ABSTRACT A series of 3-arylbenzoquinoline, pyranoquinoline, and thiopyranoquinoline derivatives have been synthesized by one-pot, multicomponentreaction of aromatic aldehyde, naphthalen-2-amine, and ketone using polyethylene glycol (PEG1000)–based dicationic acidic ionic liquid as recyclable catalyst with high yields. The PEG ionic liquid and toluene have the advantages of both homogeneous and heterogeneous
