A Pd-catalyzed selective tandem cyclization of the Ugi adduct Buchwald-Hartwig/C-H bond functionalization reactions has been reported. This sequence offers an interesting approach for synthesizing a wide range of pyrido[1,2-]pyrazine-3,6-dione scaffolds under mild reaction conditions in moderate to excellent yields. The scope and limitations of the protocol are discussed.
已报道了钯催化的Ugi加合物的选择性串联环化反应——布赫瓦尔德-哈特维希/C-H键官能团化反应。该反应序列为在温和反应条件下以中等至优异产率合成多种吡啶并[1,2 - ]吡嗪-3,6-二酮骨架提供了一种有趣的方法。本文还讨论了该方法的适用范围和局限性。
