In this investigation, an efficient and ecofriendly multicomponent reaction is described for the green synthesis of 2-amino-5-arylpyrimido[4,5-b]quinolinedione derivatives using ZrO2 (NPs). In this protocol, the reaction of 2,6-diaminopyrimidin-4(1H)-one, arylaldehyde and 1,3-cyclohexanedione or 5,5-dimethyl-1,3-cyclohexanedione in the presence of ZrO2 (NPs) in ethylene glycol at 120 °C produced the
在这项研究中,描述了使用ZrO 2(NPs)绿色合成2-氨基-5-芳基嘧啶[4,5- b ]喹啉二酮衍生物的有效且环保的多组分反应。在此协议中,在ZrO 2(NPs)存在下,2,6-二氨基嘧啶-4(1 H)-one,芳醛与1,3-环己二酮或5,5-二甲基-1,3-环己二酮的反应在120°C的条件下,乙二醇能以理想的收率(90–98%)和较短的反应时间(8–60分钟)生产出所需的产品。该方法的显着特点是使用可循环使用的催化剂,绿色溶剂,易于后处理和优异的收率。
