novel palladium-catalyzed arylation of ketone enolates with o-nitrohaloarenes was achieved through the addition of phenol additives. The mild reaction conditions employed allowed for the inclusion of a wide variety of functional groups in both substrates to be tolerated. The products of this reaction were then readily reductively cyclized to give highly substituted indoles in moderate to excellent overall
通过添加苯酚添加剂实现了一种新的钯催化的酮烯醇化物与邻硝基卤代芳烃的芳基化反应。所采用的温和反应条件允许在要耐受的两种底物中包含多种官能团。然后,该反应的产物很容易还原环化,以中等至极好的总产率得到高度取代的吲哚。
