A presente invenção relata a obtenção de compostos carbonílicos e derivados, através de sínteses com alto rendimento e pureza, proporcionando princípios ativos antitumorais com propriedades antiproliferativas seletivas e atividade antimetastática. A presente invenção refere-se ao desenvolvimento de novos butadienos push-pull polifuncionais e seus derivados O e C-prenilados, benzoilados e iodados, com alta conjugação eletrônica na cadeia lateral. Estes compostos exibem alta seletividade antitumoral, provocando a morte celular por apoptose, mostram também propriedades antimetastáticas e não mutagênicas nos estudos experimentais realizados.

Rate coefficients have been measured for the alkalinehydrolysis of 3-substituted phenyl 2-acetyl-and 2-benzoyl-benzoates in 70%(v/v) dioxane–water at several temperatures. The enthalpies and entropies of activation have been evaluated. The effects of substitution have been assessed by means of the Hammett equation. Comparison of the reaction constants with those for model systems, as well as the relative

flavones via catalytic carbonylation of aryl halides with 2‐hydroxyacetophenone using the commercial Pd/C as an efficient, heterogeneous and recyclable catalyst. Under balloon pressure of CO, 0.6 mol% Pd/C is sufficient for moderate yields of flavones for the carbonylation of aryl iodides under phosphine‐free conditions and aryl bromides in the presence of phosphine ligand. The catalyst is easily separable
