| Abstract: | A new route to N-acetyl-3-acyl-5-arylidenetetramic acids was developed and applied to the synthesis of a small library of compounds with diversity at carbon 3 of the heterocyclic ring. The 3-acetyl derivative was used as ligand for complexation with zinc(II) and copper(II) acetates. Both the ligand and the zinc complex were studied by X-ray single crystal structure analysis, the zinc complex forms ribbons by H-bonding from the ethanol to a neighbouring molecule. |
