Source of material

The title compound was synthesized according to a reported procedure [6]. A mixture of 1,3-cyclopentadione (10 mmol), 3,4,5-trimethoxybenzaldehyde (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

The H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93 Å and 0.86 Å and with Uiso(H) = 1.2 times Ueq(C) and Ueq(N).

Discussion

Since their discovery, antimicrobial drugs have proved remarkably effective for the control of bacterial infections [1]. However, it was shown that bacterial pathogens were unlikely to surrender unconditionally, because some pathogens rapidly became resistant to many of the initially used very effective drugs [2, 3].

Pyrans show a wide range of pharmacological activities, including anti-inflammatory, antimicrobial, anthelmintic and herbicidal properties. Of these, antimicrobial effects have become more important [4, 5].

In the crystal structure of the title compound, the pyran ring and the adjacent five-membered ring are both basically planar, and the two planes are also roughly parallel each other. The sp3 carbon atom C6 rules out the possibility of planarity between phenyl ring and pyran ring.
