Quinolone Derivatives

A series of new 2-quinolone derivatives linked to benzene sulphonyl moieties were performed by many steps: the first step involved preparation of different coumarins (A1,A2) by condensation of different substituted phenols with ethyl acetoacetate. The compound A1 was treated with nitric acid to afford two isomers of nitrocoumarin derivatives (A3) and (A4). The prepared compounds (A2, A3) were treated with hydrazine hydrate to synthesize different 2-quinolone compounds (A5,A6) while the coumarin treated with different amines gave compounds (A7,A8). Then the synthesized 2-quinolone compounds (A5-A8) treated with benzene sulphonyl chloride to afford new sulfonamide derivatives (A9-A12). The synthesized compounds were characterized by FT-IR, 1H-NMR, 13C-NMR spectra and by measurement some of their physical properties.

Synthesis And Characterization

This study is concerned with the synthesis and characterization of 4-thiazolidinone derivatives (3a-3e). These compounds were prepared by reacting mercaptoacetic acid with the appropriate Schiff bases (imines) by heating at 50-60 °C in chloroform with moderate yields (51- 75 %). The structures of these 4-thiazolidinone derivatives were established on the basis of spectral studies using IR, 1H-NMR, 13C-NMR, and13C-NMR DEPT .

Gewald Reaction

An efficient method is described for the synthesis of 2-methoxy-thieno[2,3-d]pyrimidin- 4(3H)-one (5) via Gewald reaction, a tandem aza-Wittig reaction and cyclization process. The key step is an aza-Wittig reaction between iminophosphorane (2), 4-chlorophenyl isocyanine and nucleophilic reagent CH3OH. Its structures were determined by means of MS, IR and 1H NMR spectra.
