    Diastereomeric Preparation of a- and b-Phenylthio Substituted N-Acylpyrazoles
    摘要:
    When 3-phenyl-l-menthopyrazole was used as a chiral auxiliary, the diastereomeric preparation of alpha- and beta-phenylthio-substituted N-acylpyrazoles (4 and 9) was accomplished in high yield by the alpha-sulfenylation using diphenyl disulfide and the conjugate addition of thiophenol, respectively.

  • Catalytic, Enantioselective Addition of Alkyl Radicals to Alkenes via Visible-Light-Activated Photoredox Catalysis with a Chiral Rhodium Complex
    作者:Haohua Huo、Klaus Harms、Eric Meggers
    DOI:10.1021/jacs.6b03399
    日期:2016.6.8
    An efficient enantioselective addition of alkyl radicals, oxidatively generated from organotrifluoroborates, to acceptor-substituted alkenes is catalyzed by a bis-cyclometalated rhodium catalyst (4 mol %) under photoredox conditions. The practical method provides yields up to 97% with excellent enantioselectivities up to 99% ee and can be classified as a redox neutral, electron-transfer-catalyzed reaction

    The optimized reaction conditions provide a good yield for the radical conjugate addition products (44 examples) with a wide range of structurally different Michael acceptors. A gram scale reaction using sunlight irradiation is also described. Furthermore, several transformations were carried out with the Giese addition products.

    The conjugate additions of N-(α,β-unsaturated)acylpyrazoles were carried out by the treatment with Grignard reagents in the presence of cuprous halides. The reaction of 2-(α,β-unsaturated)acyl-3-phenyl-l-menthopyrazoles 3a-h occurred in higher chemical yields and with asymmetric inductions on β-position, where the addition of magnesium bromide as a Lewis acid influenced to the yields and the diastereoselectivities

  • The Preparation of<i>N</i>-Acylpyrazoles and Their Behavior Toward Alcohols
    作者:Choji Kashima、Hajime Harada、Isanobu Kita、Iwao Fukuchi、Akira Hosomi
    DOI:10.1055/s-1994-25406
    日期:——
    According to four different methods, various types of N-acylpyrazoles were prepared from the corresponding pyrazoles and carboxylic acids or their acid chlorides. Although N-acylpyrazoles were inert to alcohols under neutral or weakly basic conditions, the alcoholysis was dramatically accelerated by the action of strong acid or base. On the basis of these chemical properties, the regioselective synthesis of methyl benzyl 2,2-dimethylglutarate was achieved by selective protection and functionalization of a carboxylic acid derivative using N-acylpyrazoles.
    根据四种不同的方法,从相应的吡唑和羧酸或其酰氯制备了多种类型的N-酰基吡唑。尽管在中性或弱碱性条件下,N-酰基吡唑对醇呈惰性,但强酸或碱的作用下,醇解反应显著加速。基于这些化学性质,通过选择性保护和功能化羧酸衍生物,成功实现了甲基苄基2,2-二甲基戊二酸酯的区域选择性合成。
