A series of novel pyranochromene-containing tetrazoles fused with pyrimidinethiones, pyrimidines, and diazepines 3a-f, 4a-f, and 5a-f were synthesized by condensation of the corresponding tetrazoles 2a-f with carbon disulfide, benzaldehyde, and 4-methoxy phenacyl bromide, respectively. The compound 2a-f was obtained by reaction of pyrano[3,2-c]chromenes(More)
A series of 3-substituted aminophenyl-4-hydroxycoumarins 4a-h were synthesized via Mannich reaction by using [BMIM]BF 4 ionic liquid under microwave irradiation. Compounds were characterized by IR, 1 H NMR and mass spectroscopy. All the compounds were tested for their antibacterial activity against B.subtilis, Bacillus.sp, E. coli and P.putida.
