Abstract (EN): The chromone scaffold has been found to be an important tool in the drug discovery process through its relevant pharmacological activities. Chromone carboxamide derivatives synthesized within our group have shown noteworthy results as inhibitors of monoamino oxidase-B and as ligands for adesonine receptors. Specifically, chromone-2-carboxamide has been shown to be a privileged structure for the development of selective A(3) adenosine receptor ligands. In this work two novel substituted 4-oxo-N-phenyl-4H-chromene-2-carboxamides have been synthesized and a complete structural characterization was performed using Fourier Transform Infrared Spectroscopy, one-dimensional and two-dimensional Nuclear Magnetic Resonance techniques and Mass Spectroscopy. Finally, the molecular and supramolecular structures were determined by X-ray analysis. The X-ray crystallographic analysis describes in detail the molecular conformation and supramolecular structure of a hemihydrate of 7-methoxy-4-oxo-N-phenyl-4H-chromene-2-carboxamide. The data acquired from this study add valuable information to our chromone database. The unambiguous identification of the compounds will support the understanding of the structure-activity relationships of these compounds. (C) 2013 Elsevier B.V. All rights reserved.
