    Biomimetic epoxidation in aqueous media catalyzed by cyclic dipeptides
    摘要:
    We have developed a practical epoxidation of electron-deficient enones in aqueous media using cyclic dipeptides as bioinspired green catalyst. Optimizing the reaction conditions in a triphasic system led to efficient conditions providing epoxides with good enantioselectivities. Depending on the catalyst substituent chirality, both enantiomers are obtained. The cyclic rigidity impacts significantly the enantioselectivity.

  • Asymmetric epoxidation of substituted chalcones and chalcone analogues catalyzed by α-d-glucose- and α-d-mannose-based crown ethers

    The chiral monoaza-15-crown-5 lariat ethers annellated to methyl-4,6-O-benzylidene-α-d-glucopyranoside-1 or mannopyranoside 2 have been applied as phase-transfer catalysts in the epoxidation of substituted chalcones and chalcone analogues with tert-butylhydroperoxide resulting in significant asymmetric induction. It was found that the position of the substituents in the aromatic ring of the chalcone
    与甲基-4,6- O-亚苄基-α-d-吡喃吡喃糖苷-1或甘露吡喃糖苷2甲基化的手性单氮杂-15冠-5套索状醚已被用作相取代的催化剂,用于取代的查耳酮和查尔酮类似物的环氧化与叔-butylhydroperoxide导致显著不对称诱导。发现查尔酮的芳环中取代基的位置对化学收率和对映体过量都有影响。在邻位取代的模型化合物中,对映选择性最低(62-83%ee)。在的情况下获得的最高EE值(83-97%ee)的对位替换模型。在查耳酮类似物中,对于具有α-叔丁基和β-芳基基团的模型化合物,可检测到最大ee(90-92%)。使用基于葡萄糖的冠醚1,优选形成(-)-对映体,而将基于甘露糖的2用作催化剂,则(+)-对映体过量。

    still a challenging task. In this perspective, we present the application of chiral dinuclear magnesium complexes for asymmetric epoxidation of a broad range of electron-deficient enones. We demonstrate that the in situ generated magnesium-ProPhenol complex affords enantioenriched oxiranes in high yields and with excellent enantioselectivities (up to 99% ee). Our extensive study verifies the literature
    使用更便宜且无毒的碱土金属催化剂的不对称合成正成为主要依赖贵金属的传统催化方法的重要且可持续的替代方法。尽管有一些可持续的烯酮对映选择性环氧化方法,但为这些反应开发基于镁配合物的明确且有效的催化剂仍然是一项具有挑战性的任务。从这个角度来看,我们展示了手性双核镁配合物在各种缺电子烯酮的不对称环氧化中的应用。我们证明,原位生成的镁-苯酚复合物以高产率和优异的对映选择性(高达 99% ee)提供富含对映体的环氧乙烷。我们的广泛研究验证了该领域的文献数据,并为更好地了解控制氧合过程的因素提供了一步。精心制作的催化剂提供温和的反应条件和真正广泛的底物范围。

    the objective to develop supramolecular catalysts for useful chemical transformations, we report here a rapid and efficient solid-phase synthesis of novel cyclic dipeptides (crown-CDPs) with a diversity of L-DOPA derived crown ether substituents and stereochemistry. We prepared and characterized 14 crown-CDPs and evaluated their efficiency as supramolecular epoxidation catalysts in a water/hexanes biphasic
    摘要 为了开发用于有用化学转化的超分子催化剂,我们在此报告了一种快速有效的新型环二肽(冠 CDP)的固相合成,具有多种 L-DOPA 衍生的冠醚取代基和立体化学。我们制备并表征了 14 种冠 CDP,并评估了它们在水/己烷双相体系中作为超分子环氧化催化剂的效率。尽管对映选择性取决于取代基的性质,但在冠 CDP 存在下产率显着增加。报告的结果构成了感兴趣的手性环氧化物的有用方法,并进一步说明了环肽作为超分子催化剂的潜力。
  • Highly selective multifunctional nanohybrid catalysts for the one-pot synthesis of α,β-epoxy-chalcones
    作者:Dana-Georgiana Crivoi、Anna M. Segarra、Francesc Medina
    DOI:10.1016/j.jcat.2015.11.020
    日期:2016.2
    An efficient one-pot heterogeneous process for producing chiral alpha,beta-epoxy-chalcones from the corresponding aldehydes and ketones, has been described. The nanohybrid materials based on poly-L-leucine immobilised into rehydrated hydrotalcites did not require any pre-activation and were easily recovered and recycled for four consecutive runs without losing their catalytic efficiency in terms of conversion, total selectivity towards the corresponding epoxy-chalcones and excellent enantioselectivity.
