VSM techniques. Then, 2-amino-3-cyano-4H-pyran derivatives (4a–l) as a synthetic precursor were synthesized via multi-component reaction in the presence of GO-Fc@Fe3O4 nanohybrid as a novel heterogeneous nanocatalyst. Finally, according to the importance of finding a solution to treat Alzheimer’s disease, 14-aryl-10,11,12,14-tetrahydro-9H-benzo[5,6]chromeno[2,3-b]-quinolin-13-amines (5a–l) as new
摘要 合成了功能强大且可重复使用的GO-Fc @ Fe 3 O 4纳米杂化体。用间氯过氧苯甲酸(mCPBA)处理氧化石墨烯(GO)片,然后通过GO纳米片与4-二茂铁基丁基胺之间的开环反应,用4-Fc衍生物进行化学修饰。然后,通过将Fe 3 O 4纳米颗粒合成到改性的GO表面获得最终的纳米催化剂。使用不同的分析方法,如FT-IR,XRD,FE-SEM,EDX和VSM技术对GO-Fc @ Fe 3 O 4纳米杂化物的结构和形态进行了表征。然后,2-氨基-3-氰基-4 H-吡喃衍生物(4a – l作为新型多相纳米催化剂,在GO-Fc @ Fe 3 O 4纳米杂化物的存在下,通过多组分反应合成了作为合成前体的三聚氰胺。最后,根据寻找解决阿尔茨海默氏病的方法的重要性,选择14-芳基-10,11,12,14-四氢-9 H-苯并[5,6] chromeno [2,3-b]-喹啉-13作为新的他克林-萘并吡喃杂化物类似物-胺(5a
