2,3-Diaryl quinoxaline derivatives have been efficiently synthesized by cascade, metal-free, and solvent-free reaction of aryl aldehydes with aryl 1,2-diamines initiated by N-heterocyclic carbene. Compared with reported methods, this procedure has the advantages of easy work-up, reduced energy consumption, and elimination of solvent waste, hazards, and toxicity. A group of potentially bioactive compounds has been prepared for biomedical screening.
在N-杂环卡宾的引发下,通过芳基醛与芳基1,2-二胺的级联、无金属、无溶剂反应,有效合成了2,3-二芳基喹喔啉衍生物。与报道的方法相比,该方法具有操作简便、降低能耗、消除溶剂浪费、危害和毒性等优点。一组具有潜在生物活性的化合物已被制备用于生物医学筛选。
