benzhydryl aminesfrom the reaction of readily available sulfonederivatives with amines is described. The Cu‐catalyzed desulfonylative amination not only provides structurally diverse benzhydryl amines in good yields, but is also applicable to iterative and intramolecular aminations. Control experiments suggested that the formation of a Cu‐carbene intermediate generated from the sulfone substrate,

The cross-coupling of C(sp3)–H and N–H represents one of the most straightforward approaches to construct saturated nitrogen-containing compounds. The additional oxidants or halogenated reagents are generally required in such processes. Herein, we developed an electrochemical oxidative intramolecularC(sp3)–Hamination of amides by employing a carbon rod anode and a platinum plate cathode in an undivided
We present a direct δ-amination reaction of sp3 C–H bonds, employing molecular iodine (I2) as the sole oxidant undertransition-metal-freeconditions. This remote C–H functionalization approach is operationally simple and provides facile, efficient access to pyrrolidines and related heterocyclic derivatives from readily accessible substrates.
我们提出了 sp 3 C-H 键的直接 δ-胺化反应,在无过渡金属的条件下使用分子碘 (I 2 ) 作为唯一的氧化剂。这种远程C-H官能化方法操作简单,并且可以从易于接近的底物中轻松、有效地获取吡咯烷和相关杂环衍生物。
