Abstract:
A new set of derivative thioxothiazolidinones and thioxoimidazolidinones 3,5-dissubstituted has been synthesized with satisfactory yield from the condensation Knoevenagel type between benzaldéhydes and 4-thioxothiazolidin-2-one, 2-thioxothiazolidin-4-one and 1-méthyl-2-thioxoimidazolidin-4-one compounds following by N-alkylation with aryl or acyl halides. The physico-chemical properties of the 5-benzylidene-3-[2-(4-chlorophenyl)-2-oxoethyl]-2 (or 4)-thioxothiazolidin-4 (or 2)-ones and 5-benzylidene-1-methyl-2-thioxoimidazolidin-4-ones synthesized have been described.
