heterocyclic molecules " summarizes:
- Through a bibliographical study which puts forward the heterocyclic compounds, the advantage of the reactions making their synthesis possible, in occurrence MCRs and the privilege of organic catalysis.
- Through a study of the catalytic properties of two molecules asymmetrical (DMAP and DABCO) and two symmetrical (L-Proline and Cinchonine) with respect to the synthesis of
pyrazolpyrnopyrimidindiones/ones and pyranopyrazoles, via multicomponent reactions
- Through a study of catalytic properties of two ionic liquids [MePPh3][Br] and [OPPh3][Br] in the synthesis of the spirooxindoles and the pyranopyrazoles. The results with [OPPh3][Br] are not as good as those obtained with [MePPh3][Br], which certainly due to its cumbersome properties.
- This study reinforced the idea of the organic catalysis in MCRs giving the
pyrazolopyranopyrimidindiones/ones the pyranopyrazoles and the spirooxindoles

ChimieTags : Triarylimidazoles spirooxindoles acide citrique BF3.OEt2 iminobenzimidazole fluorizoline oncogène KRAS cytotoxicité leucémie citric acid KRAS oncogene cytotoxicity leukemia Index. décimale : 540 Chimie et sciences connexes Résumé : Our work focuses on the development of new synthetic approaches to anticancer compounds. This work was carried out at the University of Constantine and Strasbourg, under Prof. Taoues Boumoud and Dr. Laurent Désaubry’s supervision. Triarylimidazoles and spirooxindoles are heterocycles found among several important anti-cancer agents. In order to facilitate the pharmacochemical exploration of these compounds, improving their synthesis was aimed. Novel catalytic ways were developped for the synthesis of triarylimidazoles and spiro[chroméne-oxindoles] with good yields via multicomponent reactions in the presence of citric acid and BF3.OEt2 as catalysts respectively. Two articles demonstarting the catalytic effects of the former catalysts in the synthesis of benzimidazoles and spirooxindole derivatives were published. Original work carried out in Strasbourg has demonstrated the cytotoxic properties of an iminobenzimidazole on cancerous lines. Analogues of this compound, were prepered, to determine the structural requirements for this cytotoxicity. An article describing these works was published inThe Open Medicinal Chemistry Journal. Another cytotoxic agent “fluorizoline” and analogues thereof were also prepared. Two first articles demonstrating the inhibition of KRAS oncogene by this compound and its activity in models of chronic lymphocytic leukemia were also published.
