    Lewis Base-Promoted Aldol Reaction of Dimethylsilyl Enolates in Aqueous Dimethylformamide:  Use of Calcium Chloride as a Lewis Base Catalyst
    摘要:
    In the presence of CaCl2, dimethylsilyl (DMS) enolates smoothly reacted with aldehydes under mild conditions to give aldol adducts in good to high yields. The catalytic activities of various metal and tetrabutylammonium salts have revealed that CaCl2 works as a Lewis base catalyst to activate DMS enolates. The CaCl2-promoted reaction proceeded even in the presence of water or in pure water. This catalytic system was applicable to the aldol reaction with aqueous aldehydes such as formalin.

  • Chiral Phosphoramide-Catalyzed Aldol Additions of Ketone Enolates. Preparative Aspects

    Trichlorosilyl enolates of ketones (enoxytrichlorosilanes) were demonstrated to be highly reactive aldol addition reagents. Trichlorosilyl enolates of cyclohexanone (E-enolate) and propiophenone (Z-enolate) reacted readily at room temperature with a wide variety of aldehydes to afford aldol addition products in high yield and diastereoselectivity (E → syn, Z → anti). These reactions were shown to be
    酮的三硅烷基烯醇化物(烯氧基三硅烷)被证明是高度反应性的羟醛加成试剂。环己酮(E-烯醇化物)和苯丙酮(Z-烯醇化物)的三硅烷基烯醇化物在室温下很容易与多种醛反应,以高产率和非对映选择性(E→syn,Z→anti)得到羟醛加成产物。这些反应被证明对催化量的手性酰胺的加速非常敏感。特别是,衍生自 (S,S)-二胺的酰胺不仅在加速反应方面显着有效,而且在调节非对映选择性和提供具有良好至优异对映选择性的羟醛加成产物方面也非常有效。未促进过程的非对映选择性已被解释为通过五配位、三角双锥 (tbp) 配合物通过船状过渡结构进行反应的结果。酰胺催化的反应更复杂,...

    asymmetric Mukaiyama aldol reactions of silicon enolates with aldehydes catalyzed by chiral FeII and BiIII complexes. Although previous reactions often required relatively harsh conditions, such as strictly anhydrous conditions, very low temperatures (−78 °C), etc., the reactions reported herein proceeded in the presence of water at 0 °C. To find appropriate chiral water‐compatible Lewis acids for the
    我们已经开发了手性Fe II和Bi III配合物催化的烯醇与醛的不对称Mukaiyama aldol反应。尽管先前的反应通常需要相对苛刻的条件,例如严格的无条件,非常低的温度(-78°C)等,但本文报道的反应是在0°C的存在下进行的。为了找到适合手性与相容的路易斯酸用于Mukaiyama醛醇缩合反应,我们筛选了许多路易斯酸与手性联吡啶L1结合,后者以前被发现是性介质中合适的手性配体。三种类型的手性催化剂,由Fe II或Bi III属盐,手性配体(L1),和添加剂已被发现和各种各样的基材(烯醇化物和醛)反应,通过三个催化体系中的一个的适当的选择,以得到所需的醛醇缩合产物以高收率和高diastereo-和对映选择性。机理研究阐明了Fe II和Bi III中心周围的配位环境以及添加剂对手性催化的影响。值得注意的是,布朗斯台德酸和碱在Fe II催化反应中都是有效的添加剂。假定的催化循

    generates highly effective chiral gallium Lewis acid catalysts for aqueous asymmetric aldol reactions of aromatic silyl enol ethers with aldehydes. A ligand-acceleration effect was observed. Water is essential for obtaining high diastereoselectivity and enantioselectivity. The p-phenyl substituent in aromatic silyl enol ether (2 h) plays an important role and increases the enantioselectivity up to 95%

    Asymmetric aldol reactions in aqueous media have been realized by using zinc-based chiral Lewis acids. The aldol products have been obtained with high yield, diastereocontrol and a good level of enantioselectivity. The reactivity of both acetophenone and propiophenone enol ether surrogates was tested with a range of aldehydes.
