afford value-added and complexity-enriched bridged bicyclic amines. Guided by density functional theory and nuclear magnetic resonance investigations, we determined the unique roles of light and heat activation in the bicyclization mechanism. We applied both light and heat activation in a synergistic fashion, achieving gram-scale bridged aza-cycle synthesis.
由于药剂中含氮杂环的普遍存在,复杂的氮杂环的构建对药物发现很重要。本文中我们报告了分子内C–H胺化方法,以提供增值和复杂性丰富的桥联双环胺。在密度泛函理论和核磁共振研究的指导下,我们确定了光和热活化在双环化机理中的独特作用。我们以协同方式应用了光和热激活,从而实现了克级桥接的氮杂循环合成。
