Menthyl 2-oxo-2H-chromene-3-carboxyl-ate.


ABSTRACT: The title compound, C(20)H(24)O(4), was synthesized from the reaction of 2-oxo-2H-chromene-3-acyl chloride and menthol. The mean plane of the ester group and that of the four essentially planar (maximum deviation 0.0112?Å) C atoms of the chair-form cyclo-hexyl ring form dihedral angles of 43.8?(3) ° and 81.8?(1)°, respectively, with the mean plane of the coumarin ring system. In the crystal structure, weak inter-molecular C-H?O hydrogen bonds connect the mol-ecules into a two-dimensional network.
