of a lead-mediated α-arylation reaction between aryl azides and β-ketoesters or γ-lactams that facilitates the formation of 3H-indoles is disclosed. Twenty-five examples are included which demonstrate the generality of this reaction to access aryl azides bearing tetrasubstituted o-alkyl substituents. When paired with a Staudinger reduction, this reaction streamlines the synthesis of functionalized 3H-indoles
公开了在芳基叠氮化物和β-酮酯或γ-内酰胺之间促进3 H-吲哚形成的铅介导的α-芳基化反应的发展。包括的二十五个例子证明了该反应的普遍性,以获得带有四取代的邻烷基取代基的芳基叠氮化物。当与施陶丁格还原配对时,该反应简化了功能化 3 H-吲哚的合成。
