镍催化的烯烃与烷基亲电试剂之间的还原交叉偶联反应是构建杂环化合物的重要方法之一. 然而, 通过还原交叉偶联反应实现烯烃芳烷基化的烷基化试剂仍相当有限. 开发以稳定且易得的起始原料, 通过还原偶联策略合成杂环化合物的更为普适的方法仍具有挑战性. 发展了一种新的镍催化还原串联芳烷基化反应: 以环硫鎓盐作为C(sp³)亲电试剂, 通过镍催化的还原偶联策略实现烯烃的芳烷基化, 从而合成了一系列含硫醚片段的氧化吲哚类化合物. 该串联开环/环化/还原偶联策略可在温和条件下高效构建多种带有全碳季碳中心的氧化吲哚, 并具有优异的官能团兼容性. 值得注意的是, 许多药物衍生物均可利用该策略直接实现官能化.

Nickel-catalyzed reductive cross-coupling (RCC) reactions between alkenes and alkyl electrophiles are undoub- tedly the attractive approaches to new functionalized heterocycles. However, the alkylation reagents are still rather limited for the arylalkylation of tethered alkenes via RCC reactions. Thus, developing more robust methods to access heterocycles from stable and readily available starting materials under RCC conditions is still highly challenging and desirable. A new nickel- catalyzed reductive arylalkylation of tethered alkenes with cyclosulfonium salts as C(sp3) electrophiles to access the sulfur- containing oxindoles is developed. This tandem ring-opening/cyclization/reductive coupling protocol enables the efficient construction of various oxindoles bearing all-carbon quaternary centers under mild conditions with broad functional group tolerance. Notably, many drug derivatives are readily functionalized using the developed protocol.
