base‐promoted nucleophilic addition of arylacetonitriles to terminal alkynes has been described for the first time, providing a simple and straightforward protocol for the synthesis of a range of structurally diverse (Z)‐2,3‐disubstituted acrylonitriles in moderate to excellent yields. Of particular note, the transition metal‐free carbon‐carbon double bond forming reaction is regio‐ and stereoselective under
首次描述了芳基乙腈在末端炔基上的碱促进亲核加成反应,为合成一系列结构多样的(Z)-2,3-二取代的丙烯腈提供了简单直接的方法,产率中等至优异。特别值得注意的是,无过渡金属的碳-碳双键形成反应在温和条件下具有区域和立体选择性。芳基乙腈底物和炔烃偶联配偶体上均可以耐受多种官能团。此外,该反应易于扩展,并且由此获得的产物可以用作用于合成一系列有用物质的通用中间体。
