Ethyl 2,2-dimethyl-4-oxo-6-phenyl-3,4-dihydro-2H-pyran-5-carboxylate
2016
The title compound, C16H18O4, is a derivative of 3,4-dihydro-2H-pyran-4-one. The plane of the pyranone ring system forms a dihedral angle of 42.76 (10)° with that of the phenyl group. The crystal structure is stabilized by C—H⋯O interactions that enclose an R21(6) ring motif and link the molecules into chains along the c axis. A short intramolecular O⋯O contact [2.942 (3) A] gives rise to an S(5) motif.
