Abstract

Due to the importance of coumarin derivatives and specially pyrano coumarins, as well as their different chemical and biological properties, we synthesized pyrano [2, 3-h] coumarins by using reactions of 5, 7-dihydroxy-4-methylcoumarin, aryl aldehydes, and malononitrile in the presence of Ti– Al/Al2 O3 nanocomposite in methanol. The structures of the products were identified by FIIR, 1 H-NMR, and 13 C-NMR spectroscopy. The excellent yields, simplicity, easy work-up and short reaction times are the most significant advantages of this method. Some antibacterial activities were evaluated via the disk diffusion method and the results showed that 8-amino-5-hydroxy-4-methyl-2-oxo-10-phenyl-2, 10-dihydropyrano[2, 3-f] chromene-9-carbonitrile (7) has significant pharmaceutical activities as antibacterial reagent comparing to Staphylococcus aureus and Escherichia coli.
