Popis:	The condensation of ethyl-2-hydroxy-4-oxo-4-(4-hydroxy-6-methyl-2-pyrone-3-yl)-2-butenoate with primary aliphatic monoamines occurs at 4-hydroxy group of the pyrone ring according to 1 HNMR and mass spectrometric data. The ketamine tautomeric form of the prepared Schiff bases is predominantly present in chloroform solutions. Isolated crude copper(II) complexes of the condensation products are shown to be mononuclear with the 1:2 metal to ligand ratio.
