Abstract

Pyrazolones (1) react with aromatic aldehydes to give 1-aryl-3 methyl-4-arylidene pyrazol-5-ones(2).. The condensation of 4-arylidene-pyrazol-5-ones (2) with thiourea/N-phenyl thiourea in alcoholic KOH led to formation of the title compounds 1, 4-diaryl-3-methyl-6-imino-4, 7-dihydro-1, 3-thiazine (5, 4-d) pyrazoles (3). The title compounds have been screened for their antibacterial activity against S.aureus and E.coli.
