  A palladium-catalyzed tandem oxidative annulation of primary benzamides with acrylates via intermolecular N-alkenylation followed by intramolecular C-alkenylation yielded a stereoselective synthesis of (E)-3-methyleneisoindolin-1-ones. The study unveils, for the first time, that only E-enamides could undergo intramolecular oxidative cyclization under the optimized conditions to give isoindolinones

  通过分子间的N-烯基化作用，然后通过分子内的C-烯基化作用，钯催化的苯甲酰胺与丙烯酸酯的串联氧化环化反应产生了（E）-3-亚甲基异吲哚啉-1-酮的立体选择性合成。该研究首次揭示，只有E-烯酰胺才能在优化条件下进行分子内氧化环化反应，得到异吲哚啉酮。与使用苯甲酰胺的文献方法相比，当前的策略代表了应有的策略。
