Cinnamyl 8-meth­oxy-2-oxo-2H-chromene-3-carboxyl­ate

In the crystal structure of the title compound, C(20)H(16)O(5), the mol­ecule assumes an E configuration with the benzene ring and chromenecarboxyl group located on opposite ends of the C=C double bond. The chromene ring system and benzene ring are oriented at a dihedral angle of 74.66 (12)°. Weak i...
