چکیده
In the title mol-ecule, C(14)H(12)O(3), the prop-2-en-1-one unit forms dihedral angles of 12.96 (5) and 7.89 (7)° with the 4-meth-oxy-phenyl group and the furan ring, respectively. The furan and benzene rings form a dihedral angle of 8.56 (5)°. In the crystal, C-H⋯π and π-π inter-actions are observed between the benzene and heterocyclic rings [centroid-centroid distance = 3.760 (1) Å].
