Their structure has been established by means of 1H and 1 C NMR spectroscopy. Homonuclear COSY and NOESY experiments and 2D-heteronuclear correlations have been performed when necessary to assign all NMR signals.application/pdfenCompuestos heterocíclicos.Artículohttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.es
