  • Osmium tetroxide–(QN)<sub>2</sub>PHAL in an ionic liquid: a highly efficient and recyclable catalyst system for asymmetric dihydroxylation of olefins
    作者:Choong Eui Song、Da-un Jung、Eun Joo Roh、Sang-gi Lee、Dae Yoon Chi

    In Os-catalysed asymmetric dihydroxylation using NMO as a co-oxidant, the combination of an ionic liquid and the new bis-cinchona alkaloid 2 generated in situ from (QN)2PHAL during reaction provided a simple and practical approach to the recycling of both catalytic components (osmium tetraoxide and chiral ligand).

  • Sc(OTf)3-catalyzed diastereoselective Friedel–Crafts reactions of arenes and hetarenes with 3-phenylglycidates
    作者:David Wilcke、Thorsten Bach
    DOI:10.1039/c2ob25988e
    日期:——
    Five different para-substituted 3-phenylglycidates (3-phenyloxirane-2-carboxylates) were prepared and subjected to reactions with arenes and hetarenes under Lewis acid catalysis. Sc(OTf)3 was found to effectively (5 mol%) promote a Friedel–Crafts reaction in nitromethane as the solvent. The reaction was shown to proceed stereoconvergently, which makes the intermediacy of a benzylic cation likely. The diastereoselectivities varied depending on the choice of the nucleophile and 3-arylglycidate. Best results were obtained with tert-butyl 3-anisylglycidate, which delivered the respective products with high syn-preference in diastereomeric ratios (d.r.) between 82 : 18 and >95 : 5. The observed selectivity can be explained by a model, according to which the intermediate benzylic cations adopt a preferred conformation, which allows for diastereoface-differentiation by the adjacent stereogenic center.
    制备了五种不同的对位取代3-苯基缩水甘油酸酯(3-苯基环氧乙烷-2-羧酸酯),并使其在Lewis酸催化下与芳烃和杂芳烃反应。发现Sc(OTf)3能有效(5摩尔%)促进以硝基甲烷为溶剂的Friedel-Crafts反应。反应呈现立体汇聚性,这表明可能存在苄基阳离子中间体。对映选择性因亲核试剂和3-芳基缩水甘油酸酯的选择而异。使用叔丁基3-茴香基缩水甘油酸酯时效果最佳,产物的顺-偏好性在外消旋体比例(d.r.)介于82:18至>95:5之间。观察到的选择性可通过一个模型解释,该模型表明中间体苄基阳离子采取的优先构象允许相邻的手性中心进行对映面区分。
  • Lipase-catalyzed transesterification as a practical route to homochiral syn-1,2-diols. The synthesis of the taxol side chain

  • Catalytic asymmetric dihydroxylation of olefins with recyclable osmate-exchanged chloroapatite catalyst
    作者:Sanjay K. Dehury、V.S. Hariharakrishnan
    DOI:10.1016/j.tetlet.2007.02.030
    日期:2007.4
    An osmate-exchanged chloroapatite (CAP-OsO4) catalyst was prepared by an ion-exchange technique. CAP-OsO4 efficiently catalyses asymmetric dihydroxylation of olefins including α,β-unsaturated esters and amides to afford the corresponding diols in high yields and enantioselectivities. The catalyst was reused for several cycles with consistent activity.
