4-Aminoquinolines have recently been indicated to be an important class of chemotherapeutic agents for artemisinin-based antimalarial combination therapy. A rapid, cheap, possibly clean and scalable route to 4-aminoquinolines endowed with multiple diversity is therefore badly needed. Classically, they have been prepared by means of SNAr reactions, requiring hazardous or costly reagents and conditions
最近表明 4-氨基喹啉是一类重要的化学治疗剂,用于基于青蒿素的抗疟联合治疗。因此,迫切需要一种快速、廉价、可能清洁且可扩展的获得具有多种多样性的 4-氨基喹啉的途径。传统上,它们是通过 SNAr 反应制备的,需要危险或昂贵的试剂和条件以及复杂的纯化程序。在本文中,微波快速加热化学表明可以将可用的 4,7-二氯喹啉有效转化为高产率和纯度的氨基喹啉库,无需进一步的纯化步骤,反应时间也很短。该文库中的一些化合物对氯喹敏感和耐氯喹的寄生虫菌株具有活性。
