Three-component condensation of 2-aminonaphthalene, acetone, and substituted benzaldehydes in alcoholic solution in the presence of concentrated hydrochloric acid gave 3-aryl-1-methylbenzo[f]quinolines. 1-Methyl-3-(nitrophenyl)benzo[f]quinolines were reduced to the corresponding amines which were converted into amides having a sulfonyl or chloroacetyl group in the aryl substituent.

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
