    名称:
    Biocatalytic asymmetric and enantioconvergent hydrolysis of trisubstituted oxiranes
    摘要:
    Asymmetric biohydrolysis of trialkyl oxiranes (+/-)-1a-3a using the epoxide hydrolase activity of whole bacterial cells proceeded in an enantioconvergent fashion and thus led to the corresponding (R)-configurated vicinal diols Ib 3b in Lip to 97% enantiomeric excess (e.e.) as the sole product. The mechanism of this enantioconvergence vas investigated by O-18-labelling experiments and it was found that both enantiomers were hydrolysed with opposite regioselectivity.

  • Methanesulfonamide: a Cosolvent and a General Acid Catalyst in Sharpless Asymmetric Dihydroxylations

    effect on the reaction time and methanesulfonamide effect. The more polar the intermediate osmate ester, the faster is the reaction without methanesulfonamide and the smaller the accelerating methanesulfonamide effect. Methanesulfonamide had no accelerating effect in the asymmetric dihydroxylation of short chain terminal aliphatic olefins as a result of easier accessibility of terminal osmate ester
    为了获得有关甲磺酰胺在Sharpless不对称二羟基化反应的解步骤中的作用的信息,在有和没有甲磺酰胺的情况下,将一系列脂族和共轭芳族烃进行了二羟基化。这项研究的假设是甲磺酰胺是一种助溶剂,有助于将根离子从相转移到有机相。的曲线吨90%比的计算分配系数堵塞P非末端脂族烃的中间渗透酸的数据显示,中间渗透酸的极性对反应时间和甲磺酰胺作用有显着影响。中间膦酸的极性越强,没有甲磺酰胺的反应越快,甲磺酰胺的促进作用越小。甲烷酰胺在短链末端脂族烃的不对称二羟基化中没有促进作用,这是由于末端膦酸基团更易于与相接触的结果。发现共溶剂假说在共轭芳族烃的不对称二羟基化反应中无效。在Sharpless不对称二羟基化反应所用的反应条件下,
  • Rh-Catalyzed Enantioselective Diboration of Simple Alkenes:  Reaction Development and Substrate Scope
    作者:Stéphane Trudeau、Jeremy B. Morgan、Mohanish Shrestha、James P. Morken
    DOI:10.1021/jo051651m
    日期:2005.11.1
    The rhodium-catalyzed reaction between bis(catecholato)diboron and simple alkenes results in the syn addition of the diboron across the alkene. The resulting 1,2-bis(boronate) is subsequently oxidized to provide the 1,2-diol. In the presence of enantiomerically enriched Quinap ligand, high enantioselection in the diboration can be achieved. The reaction is highly selective for trans- and trisubstituted alkenes and can be selective for some monosubstituted alkenes as well. The development of this reaction is described as is the substrate scope and experiments that are informative about the reaction mechanism and competing pathways.
