into N-heterocycles. The N-allylation and Ru-catalyzed ring-closing metathesis delivered the bioactive 2-arylpiperidines, Nicotiana tabacum alkaloids (R)-anatabine and (R)-anabasine in three steps. A formal synthesis of (R)-N-methylanatabine and (R)-N-methylanabasine is also completed. Graphical Abstract
摘要 具有正交双功能手柄、胺和侧链烯丙基单元的手性高烯丙基胺可以很容易地转化为 N-杂环。N-烯丙基化和 Ru 催化的闭环复分解分三步提供具有生物活性的 2-芳基哌啶、烟草生物碱 (R)-anatabine 和 (R)-anabasine。(R)-N-methylanatabine 和 (R)-N-methylanabasine 的正式合成也已完成。图形概要
