Source of material
The title compound was synthesized according to a reported procedure [4]. A mixture of 3,5-cyclohexanedione (10 mmol), 3,4,5-trimethoxy-benzaldehyde (10 mmol), malononitrile (10 mmol) and 4-(dimethylamino)pyridine (DMAP) (1 mmol) in ethanol (100 mL) was refluxed for 2-3 h and then cooled to room temperature. After filtering the precipitates, they were sequentially washed with ice-cooled water and ethanol and then dried under a vacuum.
Experimental details
Carbon-bound hydrogen atoms were placed in calculated positions and were included in the refinement in the riding model approximation, with Uiso(H) set to 1.2Ueq(C).
Discussion
Dihydropyran derivatives are widely available in nature. These derivatives exhibit various biological activities. Moreover, this kind of compounds are gaining increasing interest because of their versatile activities through chemical modifications (different substituents on the aromatic ring). Recognizing the considerable importance of the compounds, the researchers focused on the synthesis of the dihydropyran derivatives [5].
In the crystal structure of the title compound, the pyranyl moiety and the annulated ring are both basically folded (cf. the figure).
