- W2546110008 abstract "espanolSe describe la sintesis de una serie de piridazin-3(2H) onas y cinolin-3,5-diona a traves de la reaccion entre acetofenonas p-sustituidas o dimedona con acido glioxilico e hidrato de hidracina bajo irradiacion con microondas y en condiciones libre de disolvente. Las piridazinonas son sistemas heterociclicos nitrogenados de procedencia sintetica que han sido estudiados sistematicamente debido a su promisoria actividad biologica y farmacologica. La elucidacion estructural de los productos de realizo mediante analisis de RMN 1H, 13C, experimentos bidimensionales de HSQC, HMBC y espectrometria de masas. La metodologia propuesta produce buenos rendimientos en tiempos cortos de reaccion. Esto es de especial interes desde el punto de vista ambiental. EnglishThe synthesis of a series of pyridazin-3(2H)-ones and cinnolin-3,5-dione in the reaction of acetophenones p-substituted or dimedone with glyoxilic acid and hydrazine hydrate under microwave irradiation and solvent-free conditions is described. 5yridazinones are nitrogenated heterocyclic compound synthetically produced which have been systematically studied due to their promising biological and pharmacological activity. The structure of the products is based on detailed NMR analysis of experiments such as 1H, 13C, HSQC, HMBC and mass spectrometry. This methodology leads to good yields in short reaction times. This is of especial interest from the environmental point of view." @default.
