[Chemical and pharmacological research on pyran derivatives. XIII. Derivatives of 2H-pyrano/3,2-c/quinoline].
Treatment of N-alkylanilines or diphenylamine with N,N-dialkylethoxycarbonylacetamides in the presence of phosphorus oxychloride afforded 6-alkyl(phenyl)-4-dialkylaminopyrano [3,2-c] quinoline-2,5-(6H)-diones, two molecules of amide being involved in the reaction. In some instances 6-alkyl(phenyl)-4-alkylaminopyrano [3,2-c] quinoline-2,5(6H)-diones were obtained through a partial dealkylation of the amino group. Pharmacological evaluation of some compounds showed no activity on the CNS.
