Abstract: | 3H,4H-Quino[1,2-a]-2-pyrimidone, 1-(2-carboxyethyl)aminoquinolinium betaines, and methyl esters of N-quinolinyl--alanines were isolated from the reactions of aminoquinolines with methyl acrylate. Hydrolysis of the latter yielded the corresponding amino acids, two of which were converted to 1-(3- and 6-quinolinyl)dihydrouracils, and the latter was reduced to 1-(6-quinolinyl)-2-oxohexahydropyrimidine.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 482–486, April, 1971. |
