REACTION OF ARYLIDENE-2-NAPHTHYLAMINES WITH THE ETHYL ESTER OF (2-QUINOLYL)-β-OXOPROPIONIC ACID

Article abstract of DOI:10.1007/BF01184889

The reaction of arylidene-2-naphthylamines with the ethyl ester of (2-quinolyl)-β-oxopropionic acid results in the synthesis of ethyl esters of 1-(2-quinolyl)-3-arylbenzoquinoline-2-carboxylic acids.All the theoretically possible intermediate reaction products were isolated: the amino esters of 2-quinoline-β-oxopropionic acid, the hydroxy esters of tetrahydro- and esters of dihydrobenzoquinoline-2-carboxylic acid, as well as the byproducts - the ethyl ester of 2-quinolyl-α-(R-benzylidene)-β-oxopropionic acid.The IR, UV, and mass spectra of the synthesized compounds are discussed.
