Regioselective Synthesis of 2° Amides Using Visible-Light-Induced Photoredox-Catalyzed Nonaqueous Oxidative C–N Cleavage of <i>N</i>,<i>N</i>-Dibenzylanilines
protocol on 2-(dibenzylamino)benzamide to afford quinazolinones with (NH4)2S2O8 as an additive. Mechanistic studies imply that the reaction might undergo in situ generation of α-amino radical to imine by C–N bond cleavage followed by the addition of superoxide ion to form amides.
据报道,可见光驱动的光氧化还原催化的N , N -二苄基苯胺的非水氧化 C-N 裂解为 2° 酰胺。此外,我们已将此协议应用于 2-(二苄基氨基) 苯甲酰胺以提供具有 (NH 4 ) 2 S 2 O 8作为添加剂的喹唑啉酮。机理研究表明,该反应可能通过 C-N 键断裂,然后加入超氧离子形成酰胺,原位生成 α-氨基自由基为亚胺。
