Synthesis, structure, and acid-base characteristics of enaminones of the barbituric acid series

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Enaminones were obtained by a tricomponent condensation of barbituric acids, aniline and triethyl orthoformate. The acid-base properties, PMR, UV and IR spectra of 5-anilinomethylene- and 1,3-dimethyl-5-anilinomethylenebarbituric acids are discussed. The properties of these compounds conform with a bipolar structure, in which the positive charge is distributed over the exocyclic part of the molecule, while the negative charge is distributed on the Β-dicarbonyl fragment of the heterocyclic ring.
