苯并氮杂环如喹啉、喹唑啉等化合物是很多有机光电材料、药物分子和天然产物分子的核心骨架.传统上这类杂环都是以剧毒的苯胺和羰基化合物为原料通过加成、缩合等方法制备,难以实现取代基的自由调控,也容易造成环境污染,所以发展替代苯胺为原料的合成方法具有重要意义.清华大学化学系陈超课题组报道了一种全新的喹啉 Benzazepines such as quinoline and quinazoline are the core skeletons of many organic optoelectronic materials, drug molecules and natural product molecules. Traditionally, these heterocycles have been prepared by adding highly toxic aniline and carbonyl compounds as raw materials Synthesis, condensation and other methods, it is difficult to achieve the free radical regulation, but also easily lead to environmental pollution, so the development of alternative synthesis of aniline as raw materials is of great significance.Chemical Department of Tsinghua University, Chen Chao group reported a new quinoline
