The Baylis-Hillman adducts 3(a-e) and 6(a-g) were prepared by the reaction of appropriate aldehydes with alkenes in presence of catalytic amount of urotropine with ionic liquids under microwave irradiation. Structures of the newly synthesized compounds were characterized by spectral studies. The antibacterial studies of Baylis-Hilmann compounds for analysis(More)
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]BF4 ionic liquid under microwave irradiation. Compounds were characterized by IR, H NMR and mass spectroscopy. All the compounds were tested for their antibacterial activity against B.subtilis, Bacillus.sp, E. coli and P.putida. Most of the(More)
