The reaction of benzylidene-2-naphthylamine with ethyl β-(3-ethyl)-β-oxopropionate under various conditions gave the ethyl ester of α-(2-naphthylamino)benzyl-β-(3-pyridyl)-β-oxopropionic acid, 1-(3-pyridyl)-3-phenylbenzo[f]quinoline, ethyl ester of 1-(3-pyridyl)-3-phenylbenzo[f]quinoline-2-carboxylic acid, and N-(2-naphthyl)amide of β-(3-pyridyl)-β-oxopropionic acid. The IR, UV, and mass spectra of the products were studied and the pathways for their formation were discussed. 1997 Plenum Publishing Corporation.
β-oxoacids esters in the synthesis of benzo[f]quinoline derivatives

Condensation of ethyl acetoacetate and ethyl 3-oxo-3-(2-furyl-, 2-quinolyl-, 3-pyridyl)propanoates with azomethines of 2-naphthylamine series led to the formation of ethyl (3-arylbenzo[f]quinol-1-yl)acetates and of esters of the corresponding 3-aryl-1-heteryl-2-benzo[f]quinolylcarboxylic acids. The intermediate reaction products were isolated: ethyl 5-(2-naphthylamino)-3-oxo-5- phenylpentanoate, 2-[(aryl)(2-naphthylamino)methyl]-3-heteryl-3-oxopropanoates, dihydro and tetrahydro derivatives of benzoquinolylacetic and benzoquinolinecarboxylic acids.
