Ethyl (E)-3-hydroxy-2-[(4-methoxystyryl)carbamoyl]but-2-enoate

Abstract

The title compound, C16H19NO5, which was synthesized from p-methoxycinnamic acid, has intramolecular O—H...O and N—H...O hydrogen-bonding interactions. In the crystal, molecules are linked by weak C—H...O hydrogen bonds and aromatic π–π stacking interactions [minimum ring centroid–centroid separation = 3.790 (1) Å].
