Polycyclization reactions are among the most efficient synthetic tools for the synthesis of complex, polycyclic molecules in a single operation from simple starting materials. We report in this manuscript a full account on the discovery and development of a novel cationic polycyclization from readily available ynamides. Simple activation of these building blocks under acidic conditions enables the
多环化反应是从单一起始原料通过一次操作合成复杂的多环分子的最有效的合成工具之一。我们在这份手稿中报告了有关从容易获得的酰胺中发现和发展新型阳离子多环化反应的完整报告。这些构件在酸性条件下的简单活化能够产生高反应性的活化的酮
亚胺离子,从而引发前所未有的阳离子多环化反应,从而产生高度取代的多环氮杂环,该杂环最多具有七个稠合环和三个连续的立体中心。
