  • Unprecedented <i>E</i>-stereoselectivity on the sigmatropic Hurd–Claisen rearrangement of Morita–Baylis–Hillman adducts: a joint experimental–theoretical study

    first systematic investigation of the tandem mercury(II) catalysed transvinylation/Hurd–Claisen rearrangement of MBH adducts derived from alkyl acrylates. This is the first report of E-selectivity for MBH adducts with alkyl side chains and is complementary to the previously reported Johnson–Claisen and Eschenmoser–Claisen rearrangements. The rearrangement products were obtained in good yields and could
    在这里,我们报道了对串联汞(II)催化衍生自丙烯酸烷基酯的MBH加成物的跨乙烯基化/ Hurd-Claisen重排的首次系统研究。这是E的第一份报告-对具有烷基侧链的MBH加合物具有选择性,并且是对先前报道的Johnson-Claisen和Eschenmoser-Claisen重排的补充。重排产物以良好的产率获得,并且可以容易地转化为2-烯基δ-戊内酯。结合的DFT和F-SAPT研究表明,反应速率主要受非共价相互作用的支配,该非共价相互作用决定了过渡态的相对稳定性。我们的F-SAPT计算表明,超共轭作用不是那么明显,但静电相互作用是相对E  :  Z立体选择性的驱动力。
  • Rate Acceleration of the Baylis−Hillman Reaction in Polar Solvents (Water and Formamide). Dominant Role of Hydrogen Bonding, Not Hydrophobic Effects, Is Implicated
    作者:Varinder K. Aggarwal、David K. Dean、Andrea Mereu、Richard Williams
    DOI:10.1021/jo016073y
    日期:2002.1.1
    A substantial acceleration of the Baylis-Hillman reaction between cyclohexenone and benzaldehyde has been observed when the reaction is conducted in water. Several different amine catalysts were tested, and as with reactions conducted in the absence of solvent, 3-hydroxyquinuclidine was found to be the optimum catalyst in terms of rate. The reaction has been extended to other aldehyde electrophiles
    当反应在水中进行时,已观察到环己烯酮和苯甲醛之间的Baylis-Hillman反应大大加速。测试了几种不同的胺催化剂,并且与在不存在溶剂的情况下进行的反应一样,就速率而言,发现3-羟基喹核苷是最佳催化剂。该反应已经扩展到包括醛的其他醛亲电试剂。尝试将这项工作扩展至丙烯酸酯仅获得了部分成功,因为在碱催化和水促进的条件下,丙烯酸甲酯和丙烯酸乙酯迅速水解。然而,丙烯酸叔丁酯足够稳定以与相对反应性的亲电试剂偶联。有关使用极性溶剂的进一步研究表明,甲酰胺还提供了显着的加速作用,并且使用5当量的甲酰胺(最适量)比在水中进行的反应速率更快。使用甲酰胺,在Yb(OTf)(3)(5 mol%)的存在下实现了进一步的加速。新条件的范围用一系列迈克尔受体和苯甲醛以及一系列亲电试剂和丙烯酸乙酯进行了测试。讨论了速率加速的起源。
  • Enantioselective Rh-Catalyzed Hydrogenation of 3-Aryl-2-phosphonomethylpropenoates by a New Class of Chiral Ferrocenyl Diphosphine Ligands

    日期:2009.8.6
    A new class of chiral ferrocenyl diphosphine ligands with an imidazole ring, (Rc,SFc)-ImiFerroPhos, has been prepared from acylferrocenes through a five-step transformation and successfully applied in the Rh-catalyzed asymmetric hydrogenation of various 3-aryl-substituted 2-phosphonomethylpropenoates, in which a series of chiral 3-phosphono-2-arylmethylpropanoic acid derivatives were achieved in ee

    A formal synthesis of (+)-lactacystin was achieved from commercially available isobutyraldehyde and ethyl acrylate. A Baylis–Hillman reaction, an intermolecular nucleophilic displacement under Mitsunobu conditions, a Sharpless asymmetric epoxidation, a palladium(0)-catalyzed syn-selective ring opening of an epoxide by treatment with an azide, a one-pot azide reductive lactamization, and a ruthenium-catayzed
