Sodium iodide is used for the first time as a nucleophile to trap an α-imino rhodium carbene, which triggers a tandem process involving intermolecular nucleophilic attack and intramolecular SN2 reaction. A series of 5-iodo-1,2,3,4-tetrahydropyridines are obtained in high yield, and the synthetic utility of the products is demonstrated in cross-coupling reactions and the construction of biorelated polycyclic
碘化钠首次用作亲核试剂来捕获α-亚氨基铑卡宾,这引发了涉及分子间亲核攻击和分子内S N 2反应的串联过程。以高收率获得了一系列的5-碘-1,2,3,4-四氢吡啶,并且在交叉偶联反应和生物相关多环化合物的构建中证明了该产物的合成效用。
