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 one-pot synthesis of phenyl esters between N-hydroxyphthalimide (NHP) esters derived from carboxylic acid and arylboronic acids is developed. This tandem reaction underwent mild conditions with a broad range of substrates scope (up to 27 examples) in good to excellent yields (up to 93% yield). The reaction can be easily scaled up, which thus pave the way for further applications in late-stage modification
