Source of material
The title compound was synthesized according to a reported procedure [3]. A mixture of 3,5-cyclohexanedione (10 mmol), 4-methoxybenzaldehyde (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 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). Uiso(H) = 1.5Ueq(C).
Discussion
Dihydropyrans represent one of the most active classes of compounds possessing a wide spectrum of biological activities [4], [5], [6], including anticoagulant, insecticidal, anthelminthic, hypnotic, antifungal, phytoalexin, and HIV protease inhibition. Thus, dihydropyrans are attractive targets in organic synthesis [7].
In the crystal structure of the title compound, the 7,7-dimethyl-5-oxo-4H-5,6,7,8-tetrahydrobenzo[b]pyran unit is typically folded [8]. Generally all bond lengths and angles are as expected [9].
