    Access to racemic and enantioenriched 3-methyl-4-chromanones: catalysed asymmetric protonation of corresponding enolic species as the key step
    摘要:
    Bronsted acids induced the intramolecular cyclisation of 3-aryloxypropanoic esters affording 3-methyl-4-chromanones, which have been transformed into the corresponding racemic benzyl beta-oxoesters. These latter esters, in the presence of hydrogen and catalytic amounts of both palladium and (endo, endo) aminobomeol, led to optically active chromanones with up to 75% ee through a deprotection-decarboxylation-protonation cascade reaction.

  • A Family of Thiazolium Salt Derived N-Heterocyclic Carbenes (NHCs) for Organocatalysis: Synthesis, Investigation and Application in Cross-Benzoin Condensation

    A family of thiazolium salt derived N-heterocyclic carbenes (NHCs) bearing sterically demanding aryl substituents on the nitrogen and with varying backbone substitution patterns have been synthesized. Investigation of the catalytic activity of these NHCs in a number of benzoin-type coupling reactions revealed markedly different levels of reactivity and selectivity. To elucidate the underlying factors
    已经合成了一系列噻唑鎓盐衍生的 N-杂环卡宾 (NHC),在氮上具有空间要求的芳基取代基并具有不同的骨架取代模式。对这些 NHC 在许多安息香型偶联反应中的催化活性的研究表明,反应性和选择性水平明显不同。为了阐明导致反应性差异的潜在因素,对这些 NHC 催化剂的电子和空间性质进行了研究。通过使用本研究中最好的催化剂,更详细地探索了分子间交叉安息香缩合反应。
  • Highly Asymmetric NHC-Catalyzed Hydroacylation of Unactivated Alkenes

    日期:2011.5.16
    NHC‐catalysis proto(n)type: The title reaction produces 21 different chroman‐4‐one‐type products in good yields and excellent enantioselectivities, in each case building up a new all‐carbon quaternary stereocenter (see scheme). Based on DFT calculations a mechanistic scenario involving proton transfer, possible transition states, and a mode of enantioinduction is presented.

  • N-Heterocyclic Carbene-Catalyzed Hydroacylation of Unactivated Double Bonds
    作者:Keiichi Hirano、Akkattu T. Biju、Isabel Piel、Frank Glorius
    DOI:10.1021/ja906361g
    日期:2009.10.14
    An intramolecular N-heterocyclic carbene (NHC)-catalyzed hydroacylation of unactivated double bonds is reported. Systematic variation of the catalyst structure revealed an N-mesitylthiazolylidene annulated with a seven-membered ring to be especially reactive. This NHC enables a unique C-C bond-forming reaction to afford substituted chroman-4-ones in moderate to excellent yields, even ones containing all-carbon quaternary centers.

    日期:——
    An efficient synthesis of carbo- and heterocycles using CC, CO and CN bonds under cobalt catalysis is described. The substituents on olefins are key for controlling the regio- and chemoselectivity in the initial hydrogen atom transfer step and quaternary carbons are efficiently constructed under mild conditions. Cyclopropane cleavage and tandem cyclization give highly functionalized bicyclic skeletons
