  • Catalyst Repurposing Sequential Catalysis by Harnessing Regenerated Prolinamide Organocatalysts as Transfer Hydrogenation Ligands
    作者:Frederic Bourgeois、Jonathan A. Medlock、Werner Bonrath、Christof Sparr
    DOI:10.1021/acs.orglett.9b04033
    日期:2020.1.3
    A catalyst repurposing strategy based on a sequential aldol addition and transfer hydrogenation giving access to enantiomerically enriched α-hydroxy-γ-butyrolactones is described. The combination of a stereoselective, organocatalytic step, followed by an efficient catalytic aldehyde reduction induces an ensuing lactonization to provide enantioenriched butyrolactones from readily available starting
    描述了基于顺序的醛醇加成和转移氢化的催化剂再利用策略,该策略允许获得对映异构体富集的α-羟基-γ-丁内酯。立体选择性的有机催化步骤的组合,然后是有效的催化醛还原,引起随后的内酯​​化,以从容易获得的起始原料中提供对映体富集的丁内酯。通过利用脯氨酸酰胺既充当有机催化剂又充当转移加氢配体的能力,催化剂的再利用允许开发一种操作简单,经济且有效的顺序催化方法。
  • Histidine-Catalyzed Asymmetric Aldol Addition of Enolizable Aldehydes: Insights into its Mechanism
    作者:Ulf Scheffler、Rainer Mahrwald
    DOI:10.1021/jo202558f
    日期:2012.3.2
    Extensive studies of asymmetric cross-aldol addition between enolizable aldehydes are described and provide a deeper insight into histidine-catalyzed aldol additions. In particular, aspects of enantio- as well as diastereoselectivity of these reactions are discussed. Rules and predictions of configurative outcome are explained by using different transition-state models. These discussions are confirmed
    描述了可烯化醛之间不对称交叉羟醛加成的广泛研究,并为组氨酸催化的羟醛加成提供了更深入的了解。特别是,讨论了这些反应的对映选择性和非对映选择性。通过使用不同的过渡状态模型来解释配置结果的规则和预测。这些讨论已通过大量的计算得到证实。
  • Polystyrene-Supported Triphenylsilyl Chloride for the Silylation-Based Kinetic Resolution of Secondary Alcohols
    作者:Ravish K. Akhani、Robert W. Clark、Liang Yuan、Li Wang、Chuanbing Tang、Sheryl L. Wiskur
    DOI:10.1002/cctc.201500173
    日期:2015.5.18
    A silyl chloride derivatized styrene polymer was employed in the silylation‐based kinetic resolution of secondary alcohols for chromatography‐free separation of alcohol enantiomers. Synthetically useful selectivity factors were obtained; furthermore, the polymer was recycled for use in a subsequent kinetic resolution, and it maintained its selectivity and integrity.

  • Silylation-Based Kinetic Resolution of α-Hydroxy Lactones and Lactams
    作者:Robert W. Clark、T. Maxwell Deaton、Yan Zhang、Maggie I. Moore、Sheryl L. Wiskur
    DOI:10.1021/ol402982w
    日期:2013.12.20
    A silylation-based kinetic resolution has been developed for alpha-hydroxy lactones and lactams employing the chiral isothiourea catalyst (-)-benzotetramisole and triphenylsilyl chloride as the silyl source. The system is more selective for lactones than lactams, and selectivity factors up to 100 can be achieved utilizing commercially available reagents.
