We describe the synthesis of silver loaded on zirconia and its use as an efficient catalyst for a one-pot three-component reaction to synthesize 11 indenopyrimidine derivatives, of which 7 are new compounds. The procedure involves substituted benzaldehydes, indane-1,3-dione, and guanidinium hydrochloride, with ethanol as solvent. The proposed green protocol at room temperature is simple and efficient
我们描述了氧化锆负载银的合成及其作为高效催化剂的一锅三组分反应合成 11 种茚并嘧啶衍生物,其中 7 种是新化合物。该过程涉及取代苯甲醛、茚满-1,3-二酮和盐酸胍,并以乙醇为溶剂。所提出的室温绿色方案简单高效,可在短反应时间(<30 分钟)内提供优异的产率(90^-96%)。该协议按照绿色化学原理运行良好,具有高原子经济性、无需柱分离以及催化剂的可重复使用性等吸引人的特点。采用 XRD、TEM、SEM 和 BET 分析对催化剂材料进行表征。
