已经报道了从N-烷氧基酰胺合成酚酯的电化学开-关方法。这种一锅法的协议开始于使用n- Bu 4 NI(TBAI)作为电催化剂对酰胺进行快速和选择性的电二聚。在不存在电流的情况下,该反应会进一步通过酰胺催化的二聚体的Zn催化C-N键活化而进行,然后将其与苯酚偶联形成酯。本方法学不含配体,在温和的反应条件下进行。这种转变结合了多种酚和酰胺底物,导致形成功能化的酯,从而突出了其多功能性。

A hypervalentiodine-mediated intermolecular α-umpolung reaction between α-aryl- or alkyl-substituted amides and benzotriazoles or purine derivatives as N-centered nucleophiles has been established. The reaction involves sequential intra/intermolecular oxidative C–N couplings in a controlled manner, affording tetrasubstituted 3,3′-oxindoles in moderate to good yields. This approach efficiently addresses
