    Metal-Free Nitrogenation of 2-Acetylbiphenyls: Expeditious Synthesis of Phenanthridines
    摘要:
    An intermolecular nitrogenation reaction toward the synthesis of phenanthridines has been developed. This metal-free protocol provides a novel nitrogen-incorporation transformation using azides as the nitrogen source. Phenanthridines, which are of great interest in pharmaceutical and medicinal chemistry, are synthesized efficiently in one step. Moreover, the byproducts derived from the Schmidt reaction are inhibited, which further demonstrated the high chemoselectivity of this transformation.

  • Ruthenium-Catalyzed Carbon−Carbon Bond Formation via the Cleavage of an Unreactive Aryl Carbon−Nitrogen Bond in Aniline Derivatives with Organoboronates
    作者:Satoshi Ueno、Naoto Chatani、Fumitoshi Kakiuchi

    refluxing toluene gave the corresponding phenylation product in 83% yield via aryl carbon−nitrogen bond cleavage. This reaction involves two notable features: (1) the coupling proceeds via the oxidative addition of an aryl carbon−nitrogen bond in anilines to the ruthenium complex, and (2) C−C bond formation takes place via transmetalation between the Ru−NR2 species and organoboronates.

    dramatically suppressed the reduction of the aromatic ketones and, as a result, ortho-arylation products were obtained in high yield based on the aromatic ketones. In these reactions, the aliphatic ketone functioned as a scavenger of ortho-hydrogens of the aromatic ketones and the B(OR)(2) moiety of the arylboron compound (HB species). A variety of aromatic ketones, such as acetophenones, acetonaphthones
    以RuH(2)(CO)(PPh(3))(3)(3)为催化剂,芳酮与芳基硼酸酯(芳基硼酸酯)在甲苯中反应,得到相应的芳基化产物,产率适中. 在这种情况下,还形成了几乎等量的源自芳族酮还原的苯甲醇。使用脂族酮,如频哪酮和丙酮,作为添加剂或溶剂显着抑制了芳族酮的还原,因此,基于芳族酮以高产率获得邻芳基化产物。在这些反应中,脂肪族酮充当芳香族酮的正氢和芳基硼化合物(HB 物种)的 B(OR)(2) 部分的清除剂。各种芳香酮,如苯乙酮、乙萘酮、四氢萘酮、和苯并芴酮,也可用于该偶联反应。几种含有给电子(NMe(2)、OMe 和 Me)和吸电子(CF(3) 和 F)基团的芳基硼酸酯也适用于这种偶联反应。使用新戊苯酮-d(0)() 和-d(5) 的分子间竞争反应和使用新戊苯酮-d(1) 的分子内竞争反应使用3 作为催化剂进行。与分子内竞争反应相比,分子间竞争反应的 k(H)/k(D) 值有很大不同。这强烈

    作者:Paul Knochel、Tobias Korn、Matthias Schade、Murthy Cheemala、Stefan Wirth、Simon Guevara、Gérard Cahiez

    A range of aromatic organocopper or organomagnesium compounds undergo smooth cross-coupling reactions with aryl bromides, chlorides, fluorides and tosylates, leading to polyfunctionalized aromatics or heterocycles in the presence of cobalt salts (5-7.5 mol%) as catalysts. Very mild reaction conditions are needed and, in the case of cross-coupling with organocopper compounds, Bu4NI (1 equiv) and 4-fluorostyrene (20 mol%) are essential as promoters for successful couplings.

Similarly, heterocycles can be coupled and druglike structures formed.

    ortho-Substituted-2-biphenyl carboxylic acids of the type 3a–j were prepared by the tandem metalation sequence from 2-biphenyl carboxylic acid 1 with sec-butyllithium in THF at −78°C followed by quenching with electrophiles. The carboxylic acids 3a–f were converted into 1-substituted fluorenones 4a–f upon treatment with methanesulfonic acid.
