    Stereoselective hetero Diels–Alder reactions of chiral tricarbonyl (η6-benzaldehyde)chromium complexes
    摘要:
    The ZnCl2-promoted cycloaddition of a series of enantiopure ortho-substituted benzaldehyde-Cr(CO), complexes and Danishefsky's diene gave the corresponding 2-aryl pyranones in good yields and complete enantio specificity. Some of the mechanistic aspects of the cycloaddition were investigated and the reaction extended to different dienes. (C) 2001 Elsevier Science Ltd. All rights reserved.

  • Chiral Chromium Salen@rGO as Multipurpose and Recyclable Heterogeneous Catalyst

    to promote asymmetric catalysis in repeated cycles, without loss of activity or enantioselectivity. This specific behavior was demonstrated in two different catalytic reactions (up to ten reuses) promoted by chromium salen complexes, the cyclohexene oxide ring-opening reaction and the hetero-Diels-Alder cycloaddition between various aldehydes and Danishefsky's diene. Furthermore, the chiral chromium
    描述了通过 π-π 非共价相互作用在还原氧化石墨烯 (rGO) 上首次固定芘标记的铬萨伦复合物。获得了非常强大的负载催化系统,以促进重复循环中的不对称催化,而不会损失活性或对映选择性。这种特殊行为在由铬盐络合物促进的两种不同催化反应(最多十次重复使用)中得到证明,即氧化环己烯开环反应和各种醛与丹麦谢夫斯基二烯之间的杂-Diels-Alder 环加成反应。此外,已发现手性铬 salen@rGO 与多底物类型的使用兼容,其中每次重复使用催化剂时都会修改所涉及的底物结构。

    products with very high enantioselectivity (up to 99% ee) and yield (92%). The hetero-Diels-Alder reaction of other aldehydes with 1 under the catalysis of TiHBOL is a general reaction which proceeds well with very high enantioselectivity and isolated yield for various aldehydes at 0 degrees C to room temperature. Based on the experimental results, the proposed mechanism of the hetero-Diels-Alder reaction

    A process for performing a catalytic Diels-Alder reaction by reacting a diene with a dienophile in the presence of a heterogeneous catalyst comprising a zeolitic material exchanged or impregnated with ions of a Lewis acidic metal is described. The catalyst, for example, copper-exchanged zeolite Y, may be treated with chiral bis(imine) compounds to direct the chirality of the reaction products. The catalyst can be separated from the reaction mixture and re-used in further Diels Alder reactions.
