affording a convenient method for the preparation of N-aryl substituted 3-chloroquinoxalin-2-amines. A related N-benzyl derivative, however, was prepared via a conventional method. These N-alkyl/aryl substituted 3-chloroquinoxalin-2-amines on coupling with terminal alkynes in toluene under Pd/C–Cu catalysis afforded a range of 1,2-disubstituted pyrrolo[2,3-b]quinoxalines within 3–5 h in good to excellent
AlCl 3促进2,3-二氯喹喔啉和苯胺之间的C–N键形成反应,为制备N-芳基取代的3-氯喹喔啉-2-胺提供了一种方便的方法。然而,通过常规方法制备了相关的N-苄基衍生物。在Pd / C-Cu催化下,这些N-烷基/芳基取代的3-氯喹喔啉-2-胺与末端炔烃在甲苯中的偶合作用提供了1,2-二取代的吡咯并[2,3- b在3-5小时内产生]喹喔啉,收率为好至优。在体外针对两种癌细胞系进行测试时,某些合成的化合物显示出令人鼓舞的抗增殖特性。对接研究表明,这些分子与人Akt在计算机上相互作用良好。
