The crystal and molecular structure of the title compound, C 19 H 20 Cl 2 O 2 , reveals a chair conformation for the pyran ring in which the hydroxyl group is axially oriented. All the other substituents occupy equatorial positions. There are two molecules in the asymmetric unit.
In the title compound, C 16 H 18 N 2 O 4 , the cyclohexene ring adopts a half-chair conformation. In the solid state, intermolecular O-HÁ Á ÁN hydrogen bonds link the molecules into dimers. The crystal packing is further stabilized by N-HÁ Á ÁO and O-HÁ Á ÁO hydrogen bonds and weak C-HÁ Á ÁO interac
