提出了一种由N-芳基哌啶或N-芳基氮杂环庚烷的级联反应合成吡咯烷-2-甲醛或四氢吡啶-2-甲醛的新方法。从机理上讲,标题化合物的形成涉及通过Cu(OAc)2 / KI / O 2促进的氧化裂解和C–N键的重整,使灭活的环状胺发生前所未有的氧化环收缩。有趣的是,当用PhI(OAc)2代替KI时,可以高效地直接获得相应醛的1,1-二乙酸酯。据我们所知,这是区域选择性C(sp 3)–H键功能化和C(sp 3)–使用铜盐和氧使饱和环胺的N键活化。

a novel and efficient α-C(sp3)–H alkenylation of cyclic amines with maleimides. Mechanistically, this C(sp3)–H/C(sp2)–H cross dehydrogenative coupling (CDC) reaction involves a cascade procedure including oxidative α-amino radical formation from the cyclic amine substrate and nucleophilicaddition of the in situ formed α-amino radical onto the electron-deficient carbon–carbon double bond of maleimide

and efficient synthesis of furan‐2(5H)‐one fused N,O‐containing bicyclic compounds via the cascade reactions of N‐aryl substituted cyclic amines with 2‐oxo‐2‐arylacetic acids is presented. Mechanistically, the formation of the title compounds is initiated by the in situ formation of a cyclic enamine intermediate via FeCl3/di‐tert‐butyl peroxide (TBP)/oxygen (O2)‐promoted C(sp3)−H dehydrogenation of saturated
