A convenient CuI/L-proline-catalyzed, two-step one-pot method has been developed for the preparation of indolo[1,2-a]quinazoline derivatives using a sequential Ullmann-type C–C and C–N coupling. This protocol provides an operationally simple and rapid strategy for preparing indolo[1,2-a]quinazoline derivatives and displays good functional group tolerance. All the starting materials are commercial available or can be easily prepared.
已开发出一种便利的CuI/L-脯氨酸催化的两步一锅法,用于制备吲哚[1,2-a]喹唑啉衍生物,采用顺序的Ullmann型C-C和C-N偶联。该方案提供了一种操作简单且快速的策略,用于制备吲哚[1,2-a]喹唑啉衍生物,并展现出良好的官能团容忍性。所有起始原料均为商业可得或易于制备。
