  • Sodium Butylated Hydroxytoluene (NaBHT) as a New and Efficient Hydride Source for Pd‐Catalysed Reduction Reactions
    作者:Sepideh Sharif、Michael J. Rodriguez、Yu Lu、Michael E. Kopach、David Mitchell、Howard N. Hunter、Michael G. Organ

    for the efficient arylation of various base-sensitive amines and (hetero)aryl halides has been found to have an unanticipated role as a hydride donor to reduce (hetero)aryl halides and allylic acetates. Mechanistic studies have uncovered that NaBHT, but not BHT, can deliver multiple hydrides through oxidation of the benzylic methyl group in NaBHT to the aldehyde. Further, performing the reduction with
    NaBHT(丁基羟基甲苯钠),一种受阻且可溶的碱,用于各种碱敏性胺和(杂)芳基卤化物的有效芳基化,已发现其作为氢化物供体的作用是出乎意料的,以减少(杂)芳基卤化物和乙酸烯丙酯。机理研究发现,NaBHT而非BHT可以通过将NaBHT中的苄基甲基氧化为醛来递送多种氢化物。此外,用NaBHT-d20进行还原已经表明,氧化还原活性苄基位置不是来自NaBHT的唯一氢化物供体位点,其中三分之一的氢化物可能来自叔丁基。在温和的条件下,还原效果很好,而且令人难以置信的是,在此过程中仅消耗了20%的NaBHT。其余的80%可以很容易地以纯净的形式回收再利用。这,

    effective for a wide range of arenes, including nonactivated arenes bearing simple functionalities such as fluoride, chloride, ester, amide, ether, nitrile, and trifluoromethyl groups as well as heteroarenes including indole, thiophene, pyridine, and isoquinoline. An analogous C-H azidation is also accomplished using azidoiodinane for direct introduction of a useful azide group onto a broad scope of arenes
    芳烃胺化是通过位点选择性 CH 锌化,然后在温和条件下铜催化与 O-苯甲酰羟胺偶联来实现的。这一成功的关键是由氨基二乙基锌酸锂介导的邻位锌化,它对多种芳烃有效,包括带有简单官能团的非活化芳烃,如氟化物、氯化物、酯、酰胺、醚、腈和三氟甲基以及杂芳烃包括吲哚、噻吩、吡啶和异喹啉。类似的 CH 叠氮化也可以使用叠氮碘来完成,将有用的叠氮基团直接引入到广泛的芳烃和杂芳烃上。这些新的转化提供了快速获得有价值且多样化的氨基芳烃化学空间的途径。通过后期胺化和叠氮化反应合成天然产物 (-)-尼古丁和抗抑郁药舍曲林的新型类似物,证明了它们在有机合成和药物发现中的广泛应用。
  • Rhenium‐Catalyzed Arylation–Acyl Cyclization between Enol Lactones and Organomagnesium Halides: Facile Synthesis of Indenones

    A set of rhenium-catalyzed arylation–acyl cyclizations between (hetero)arylmagnesium halides and enol lactones through a cascade C(sp2)−C(sp2)/C(sp2)−C(sp2) bond formation under mild reaction conditions has been developed. Indeed, a wide range of functional groups on both organomagnesium halides and enol lactones is well tolerated by the simple rhenium catalysis, thus furnishing polyfunctionalized
    (杂)芳基卤化镁和烯醇内酯之间通过在温和反应下形成级联 C(sp 2 )-C(sp 2 )/C(sp 2 )-C(sp 2 ) 键形成的一组铼催化的芳基化-酰基环化条件已经开发。事实上,有机镁卤化物和烯醇内酯上的各种官能团都可以被简单的铼催化很好地耐受,从而以一锅法提供多官能化茚酮,并完全控制区域选择性。此外,该方法还为新木脂素和 (iso) pauciflorol F 提供了一种直接的合成途径。机理研究表明,该反应涉及一系列顺碳化和分子内亲核加成。

    5-Alkoxy-1,2,4-triazolo[4,3-c]pyrimidine-3(2H)-thione compounds, such as 5-ethoxy-8-fluoro-1,2,4-triazolo[4,3-c]pyrimidine-3(2H)-thione, were prepared by cyclization of 2-alkoxy-4-hydrazinopyrimidine compounds, such as 2-ethoxy-5-fluoro-4-hydrazinopyrimidine, with carbon disulfide and hydrogen peroxide. The reaction can be carried out in the presence of a trialkylamine, such as triethylamine, in which case a trialkylammonium salt is obtained. The products are useful intermediates in the preparation of 5-alkoxy[1,2,4]triazolo[1,5-c]pyrimidine-2-sulfonamide herbicides.

    5-Alkoxy[1,2,4]triazolo[1,5-c]pyrimidine-2 (3H)-thione compounds, such as 5-ethoxy-8-fluoro[1,2,4]triazolo[1,5-c]pyrimidine-2(3H)-thione, were prepared by treatment of a 5-alkoxy-1,2,4-triazolo-[4,3-c]pyrimidine-3(2H)-thione compound, such as 5-ethoxy-8-fluoro-1,2,4-triazolo[4,3-c]pyrimidine-3(2H)-thione, with an alkali metal alkoxide in an alcohol solvent selected so that the 5-alkoxy group, the alkoxide, and the alcohol all have the same alkyl group. The trialkylammonium salts of the 5-alkoxy-1,2,4-triazolo [4,3-c]pyrimidine-3(2H)-thione compounds were converted to 3-hydrocarbylthio-5-alkoxy-1,2,4-triazolo-[4,3-c]pyrimidine compounds by reaction with a hydrocarbyl halide, such as benzyl chloride. The products are useful intermediates in the preparation of 5-alkoxy[1,2,4]triazolo[1,5-c]pyrimidine-2-sulfonamide herbicides.
