Abstract: Diarylidene ketones 1a-c, prepared by the condensation of acetone with different appropriate aldehydes, on Michael addition with 1,3-diphenyl-thiobarbituric acids afford the desired spiro compounds 2a-c. The diarylidene derivatives 3a-l undergo cyclisation with hydrazine, phenyl hydrazine, hydroxylamine, urea and guanidine carbonate to furnish pyrazole 4a-l, phenyl pyrazole 5a-l, isoxazole 6a-l, pyrimidine 7a-l, and aminopyrimidine 8a-l compounds, respectively. The structures of all the compounds have been confirmed on the basis of their analytical, IR, NMR and Mass spectral data. The antimicrobial activities
