Herein, we report the nickel-catalyzed denitrogenative cyclization reaction of 1,2,3,4-benzothiatriazine-1,1-dioxides with arynes to generate the polysubstituted biaryl sultams with tolerance of a wide diversity of substituents on every subunit. The mechanistic study indicates that the reaction is initiated by the formation of a diradical species, which reacts with a nickel complex to form a nickelacycle

Herein, a novel Pd-catalyzed denitrogenation/vinylation of benzotriazinones using vinylenecarbonate as the vinylation reagent is reported. This transformation demonstrates an unprecedented skeletal editing approach, effectively converting NN to CC fragments in situ and synthesizing a collection of isoquinolinones with broad-spectrum functional group tolerance. Moreover, the quite concise reaction
在此,报道了一种使用碳酸亚乙烯酯作为乙烯基化试剂的新型钯催化苯并三嗪酮脱氮/乙烯基化反应。这种转变展示了前所未有的骨骼编辑方法,有效地将 N N 至 C C原位片段并合成一系列具有广谱官能团耐受性的异喹啉酮。此外,相当简洁的反应体系和生物活性分子的后期修饰全面强调了该方案的实际潜力。
