Microwave-mediated N-arylation of 4-chloroquinazolines in THF/H2O rapidly and efficiently afforded a library of novel 6-halo-2-phenyl-substituted 4-anilinoquinazolines. The methodology was compatible with numerous ortho-, meta-, and para-substituted N-methylanilines as well as substituted anilines and furnished the corresponding 4-anilinoquinazolines in good yields. Preliminary screening of the synthesized
微波介导的 4-氯喹唑啉在 THF/H 2 O 中的N-芳基化快速有效地提供了一个新型 6-卤代-2-苯基取代的 4-苯胺基喹唑啉库。该方法与许多邻位、间位和对位取代的N-甲基苯胺以及取代的苯胺兼容,并以良好的收率提供了相应的 4-苯胺基喹唑啉。针对肿瘤细胞(HCT-116 和 T98G)的合成化合物的初步筛选显示出有希望的抗增殖特性。
