Abstract

In an effort to develop new antimicrobial agents, 3-(4-methylcoumarin-7- yloxyacetylamino)-2-thioxo-1,3-thiazolidin-4-one (4) was synthesized by reaction of thiocarbonylbisthioglycolic acid with ethyl (4-methyl-2-oxo-2H-chromen-7-yloxy)acetohydrazide (3), which was prepared in turn from 7-hydroxy-4-methylcoumarin (1). The condensation of compound 4 with different aromatic aldehydes afforded a series of 5-(arylidene)-3-(4-methylcoumarin-7-yloxyacetyl-amino)-2-thioxo-1,3-thiozolidin-4-one analogs 5a-h. The structures of these synthetic compounds were elucidated on the basis of IR, 1H-NMR and 13C-NMR spectral data and ESI-MS spectrometric analysis. Compounds 5a-h were examined for their antibacterial activity against several strains of Gram-positive and Gram-negative bacteria.
