中文摘要: 本项目拟研究氮原子α位C-H键的官能团化反应,探索和发展基于1, 5-负氢迁移参与的新的反应模式。利用Lewis酸或者Brønsted酸作为催化剂,实现1, 5-负氢迁移参与的吡咯和吲哚的芳构化反应,其次将含双亲核位点的亲核试剂引入到1, 5-负氢迁移参与的反应当中,实现1, 5-负氢迁移参与的去芳构化反应。将所发展的方法学应用到一些具有生物活性的杂环化合物的合成中,并将其中新颖的反应发展为不对称的反应。

英文摘要: This project focuses on development of C-H functionalization for α-position of nitrogen atom, exploring new reaction strategies involving [1, 5]-hydride shift reaction. This project includes two parts, first of all, with using Lewis acids or Brønsted acids as catalysts, realizing pyrrole and indole aromatization reaction involving [1, 5]-hydride shift reaction. Next, nucleophiles containing two nucleophilic sites are employed to the reaction that involve [1, 5]-hydride shift reaction, realizing dearomatization reaction involving [1, 5]-hydride shift reaction. Finally, the developed methodologies were applied to synthesis of heterocyclic compounds with biological activity, and the novel reaction was developed to asymmetric version.
