using silver nanoparticles (AgNPs) as a high performance nanocatalyst in H2O/EtOH at 60°C afforded the corresponding polyfunctionalized benzo[h]pyrazolo[3,4‐b][1,6]naphthyridines 5a‐h and benzo[g]pyrazolo[3,4‐b]quinolines 6a‐i, respectively. Excellent catalytic activity, high yields, employing green media and green nanocatalyst, cost‐effective and simple procedure are some notable advantages of using
一种高效简单的芳基乙二醛一水合物1a-h,5-氨基-1-芳基-3-甲基吡唑2a,b和4-羟基喹啉-2(1 H)-一的三组分反应方案(3)或2-羟基-1,4-萘醌(4使用银纳米颗粒(的AgNPs)如在H高性能纳米催化剂)2 O / EtOH中在60℃下,得到相应的多官能化苯并[ ħ ]吡唑并[3,4- b ] [1,6]萘啶5a‐h和苯并[ g ]吡唑并[3,4‐ b ]喹啉6a‐i, 分别。在这种合成策略中,将AgNPs用作贵金属纳米催化剂具有出色的催化活性,高收率,采用绿色介质和绿色纳米催化剂,具有成本效益且操作简单的优点。稠合杂环的结构通过其傅立叶变换红外光谱,质子核磁共振(1 H-NMR),13 C-NMR光谱数据和显微分析得到证实。
