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

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

The title compound, C19H14O4, was prepared by the reaction of 2-oxo-2H-chromene-3-acyl chloride with cinnamic alcohol. The whole molecule is not planar, the dihedral angle between the planes of coumarin and benzene rings being 13.94 (4)°, but the plane of the coumarin ring...
