the method was investigated by N-arylation using reaction of amines with hydroxybenzotriazole as a novel phenylating reagent, one-pot synthesis of imidazoheterocycles by a three-component reaction of 2-aminopyridine, aldehyde, terminal alkyne and preparation of tetracyclic quinazolinone ring by one-pot reaction of isatoic anhydride, amine, and ninhydrin. High yields, low cost of catalyst, environmental
在本研究中,肽纳米纤维用于固定氧化锌。该纳米颗粒是通过在水溶液中自组装制备的。通过FT-IR、EDS、SEM、TEM、XRD、ICP-OES(电感耦合等离子体发射光谱法)和紫外-可见光(UV-Vis)等一系列技术对制备的催化剂的结构性质进行了检测。光谱学。TEM 图像显示了用氧化锌装饰的肽纳米纤维的项链模型。该方法的通用性通过使用胺与羟基苯并三唑的反应作为新型苯化试剂的N-芳基化,通过2-氨基吡啶、醛、末端炔的三组分反应一锅合成咪唑杂环和制备四环喹唑啉酮环来研究该方法的通用性通过靛红酸酐、胺和茚三酮的一锅反应。
