Abstract 1-Phenyl-4-carboxymethylmercapto-5-arylazo-hydantoin derivatives (3a-f) were cyclised with acetic anhydride to give the bicyclic products (4a-f). Compounds 4 a, b condensed with aromatic aldehydes in acetic acid and in presence of anhydrous sodium acetate yielding the corresponding arylidene derivatives (5a-c). Compounds 4a, b also couple with aryldiazonium salts to give the expected coloured arylazo compounds (6a-j). 4 a, b reacted with formaldehyde and primary aromatic amines in ethanol to give the corresponding Mannich bases (7a-f).

Convergent and convenient regioselective synthesis of novel thiazolo[2,3-a]pyrimidines was accomplished using the one-pot reaction of 6-ethylthiouracil, bromoacetic acid, anhydrous sodium acetate, acetic anhydride, acetic acid and suitable aldehyde.

3-Methylpyrazol-5-one3reacts with substituted benzaldehydes4a-din the presence of anhydrous sodium acetate to produce the corresponding 4-arylidene-5-methyl-2,4-dihydro-pyrazol-3-ones5a-dand the condensation of5a-dwith 2-bromoalkoxy-1H-isoindole-1, 3-(2H)-diones2a-cfurnished corresponding 2-[2-(4-arylidene-3-methyl-5-oxo-4,5-dihydro-pyrazol-1-yl)alkoxy]-isoindole-1,3-diones6a-l, which on cyclisation with o-phenylendiamine give titled compounds7a-l. All the synthesized compounds have been characterized by elemental analysis and spectral data and screened for their antibacterial properties against various bacterial strains in order to obtain chemotherapeutic properties.

New six unexpected 1,3,4-oxadiazoles were obtained starting from acylthiosemicarbazides. N1-[4-(4-X-phenylsulfonyl)benzoyl]-N4-(2/3-methoxyphenyl)-thiosemicarbazides 2,3a-c were treated with ethyl chloro- or bromoacetate in presence of anhydrous sodium acetate in order to obtain new thiazolidin-4-ones compounds. However, formation of desired thiazolidin-4-ones from these acylthiosemicarbazides failed and instead 1,3,4-oxadiazoles were obtained. For confirmation presence of these compounds, 5-[4-(phenylsulfonyl)phenyl]-2-(3-methoxyphenylamino)-1,3,4-oxadiazole 5a was synthetized by cyclodesulfurization of acylthiosemicarbazide 3a with mercury (II) acetate. The structures of these compounds were elucidated by FTIR, UV, 1H-NMR and 13C-NMR, MS spectra and elemental analysis.
