KO<sup><i>t</i></sup>Bu-Mediated Aerobic Transition-Metal-Free Regioselective β-Arylation of Indoles: Synthesis of β-(2-/4-Nitroaryl)-indoles
flask. By using this mild and economical methodology, syntheses of β-(2/4-nitroaryl)-indoles with sensitive functionalities such as bromo, iodo, cyano, and nitro were achieved chemo- and regioselectively. Synthesized β-(2/4-nitroaryl) indoles were transformed into densely functionalized biindoles, indoloindoles, and (4-aminoaryl)-indoles which demonstrate post-transformation utility of the developed methodology
在室温下,在开放式烧瓶中的DMSO中,存在KO t Bu介导的硝基芳烃与吲哚的分子间氧化C–C偶联。通过使用这种温和且经济的方法,可以选择性地实现具有溴,碘,氰基和硝基等敏感功能的β-(2 / 4-硝基芳基)-吲哚的合成。合成的β-(2 / 4-硝基芳基)吲哚被转化为高密度官能化的双吲哚,吲哚吲哚和(4-氨基芳基)-吲哚,证明了所开发方法的转化后效用。

Pyridin‐2‐ol‐N‐oxide was designed as an efficient ligand for the couplingreaction of aryl iodides, aryl bromides and aryl chlorides, respectively, with primary amines, cyclic secondary amines or N‐containing heterocycles at room or moderate temperature. The catalytic system showed great functional groups tolerance and excellent selective reactivity.

bond formationreactions via acylnitrene transfer have recently attracted much attention, but direct detection of the proposed acylnitrenoid/acylimido M(NCOR) (R=aryl or alkyl) species in these reactions poses a formidable challenge. Herein, we report on Ru(NCOR) intermediates in C−N bond formation catalyzed by [RuIV(Por)Cl2]/N3COR, a catalytic method applicable to aziridine/oxazoline formation from

A magnetically retrievable, efficient, and benign maghemite‐Cu nanocatalyst was synthesized from inexpensive precursors and applied for C−O, C−N, and C−S bond‐formation reactions. The obtained maghemite‐Cu nanocatalyst was characterized by various techniques such as XRD, X‐ray photoelectron spectroscopy, field‐emission gun SEM with energy‐dispersive spectroscopy, atomic absorption spectroscopy, TEM
