    Regioselective Synthesis of 2H-Indazoles Using a Mild, One-Pot Condensation–Cadogan Reductive Cyclization
    摘要:
    An operationally simple and efficient one-pot synthesis of 2H-indazoles from commercially available reagents is reported. Ortho-imino-nitrobenzene substrates, generated via condensation, undergo reductive cyclization promoted by tri-n-butylphosophine to afford substituted 2H-indazoles under mild reaction conditions. A variety of electronically diverse ortho-nitrobenzaldehydes and anilines were examined. To further extend the scope of the transformation, aliphatic amines were also employed to form N2-alkyl indazoles selectively under the optimized reaction conditions.

  • Integrating Allyl Electrophiles into Nickel‐Catalyzed Conjunctive Cross‐Coupling
    作者:Van T. Tran、Zi‐Qi Li、Timothy J. Gallagher、Joseph Derosa、Peng Liu、Keary M. Engle

    日期:2020.4.27
    offer exciting possibilities in organic synthesis but remains largely unknown. Herein, we report the use of allyl electrophiles in nickel-catalyzed conjunctive cross-coupling with a non-conjugated alkene and dimethylzinc. The transformation is enabled by weakly coordinating, monodentate aza-heterocycle directing groups that are useful building blocks in synthesis, including saccharin, pyridones, pyrazoles
    烯丙基化和联合交叉偶联代表了催化中两种有用但很大程度上不同的反应范式。这两个过程的结合将为有机合成提供令人兴奋的可能性,但仍然很大程度上未知。在此,我们报道了烯丙基亲电子试剂在镍催化的与非共轭烯烃和二甲基锌的连接交叉偶联中的应用。这种转化是通过弱配位的单齿氮杂环导向基团实现的,这些导向基团是合成中有用的结构单元,包括糖精、吡啶酮、吡唑和三唑。该反应在温和条件下发生,并且与多种烯丙基亲电子试剂兼容。起始材料的 β-γ 烯烃的容易反应性证明了通过底物方向性实现的高化学选择性,而产物的 ϵ-ζ 烯烃被保留。通过开发炔烃底物的类似方法,进一步说明了这种方法的普遍性。机理研究揭示了弱配位导向基团解离对于允许烯丙基部分结合并促进 C(sp3 )-C(sp3 ) 还原消除的重要性。
  • The Stereochemistry of Organometallic Compounds. XLII. The Preparation of [2,1-b]Quinazolines Involving Rhodium-Catalysed Hydroformylation of 2-Amino-N-Alkenylbenzylamines
    作者:EM Campi、J Habsuda、WR Jackson、CAM Jonasson、QJ Mccubbin
    DOI:10.1071/ch9952023
    日期:——

    Rhodium-catalysed reactions of 2-amino-N-alkenylbenzylamines with H2/CO give hexahydro-pyrrolo- and hexahydropyrido -[2,1-b] quinazolines. Reactions of N-allyl derivatives give a single regioisomer, and reactions of but-3-enyl analogues give mixtures of pyrrolo and pyrido derivatives. Some reactions give significant amounts (10-30%) of tetrahydro derivatives. The origin of these compounds remains unclear.
