(E)-3-(2,3-Dimethoxyphenyl)-1-(2-hydroxy-4-methoxyphenyl)prop-2-en-1-one
The mol-ecular conformation of the title compound, C(18)H(18)O(5), is stabilized by a strong intra-molecular hydrogen bond between the hydroxyl and carbonyl groups. The C=C double bond displays an E configuration while the carbonyl group shows an S-cis configuration relative to the double bond. The dihedral angle between the two rings is 15.0 (1)°.

In the title mol-ecule, C(14)H(16)N(2)O(3), the heterocyclic ring adopts a flattened boat conformation, and the plane through its four coplanar atoms makes a dihedral angle of 89.65 (7)° with the benzene ring. The non-H atoms of the carbonyl, acetyl and methyl groups are nearly coplanar with the attached heterocyclic ring. Inter-molecular N-H⋯O and C-H⋯O hydrogen bonds are present in the crysta...
