were prepared via combination of D-fructose with urea and L-aspartic acid or L-arginine. After identification, the catalytic activity of these mixtures, was evaluated in the one-pot multi-component synthesis of tetrahydro-1,2,4-triazolo[5,1-b]quinazolin-8(4H)-one derivatives. In the presence of both prepared mixtures the desired products were obtained with high diversity from the reaction of 3-amino-1
在本研究中,通过D-果糖与尿素和L-天冬氨酸或L-精氨酸的组合制备了两种新的低共熔混合物。经鉴定,这些混合物在四氢-1,2,4-三唑并[5,1- b ]喹唑啉-8(4 H )的一锅法多组分合成中评价其催化活性。)-一种衍生物。在两种制备的混合物存在下,通过 3-氨基-1,2,4-三唑、芳香醛和双甲酮或环己二酮的反应,在短反应时间内以良好的产率获得了具有高度多样性的所需产物。所报道的方法具有催化剂制备容易、工艺绿色、成本效益和后处理程序简单等显着特点。此外,催化剂易于回收,可循环使用多达五次,而不会显着损失其活性。
