    摘要:
    发现纳米磁性负载的磺酸是有效合成嘧啶酮的强大且可重复使用的非均相催化剂。在这项研究中,我们在比吉内利类似反应的一锅法合成嘧啶酮中使用了各种酮类(例如苯乙酮和环戊酮)代替了β-酮酯。我们的目标是改善在无溶剂条件下使用纳米磁性催化剂合成多组分反应的条件。已经开发出许多优异和显着的结果,这使我们的观点理解了磁性纳米颗粒用作催化剂时的效果。

    used as a catalyst for the synthesis of a series of 2H-indazolo[2,1-b]phthalazine-triones and Biginelli-like products. It was observed that only 10 mg of the catalyst was enough to catalyze these reactions under mild conditions, and the corresponding products were obtained in high to excellent yields. Moreover, the catalyst could be repeatedly used for at least five times without a noticeable decrease
