    The attempted stereoselective synthesis of chiral 2,2′-biindoline
    摘要:
    The attempted first stereoselective synthesis of 2,2'-biindoline using a metathesis-Sharpless asymmetric dihydroxylation strategy results in the synthesis of the heterocycle in poor to modest stereoselectivity. Attempts to improve the ee by varying the heteroatom protecting groups in key intermediates did not enhance the outcome of the Sharpless AD reaction. Therefore a limitation of this AD reaction is the use of 1,4-substituted but-2-enes where these substituents are ortho-substituted aromatics. Crown Copyright (C) 2010 Published by Elsevier Ltd.

  • Synthesis of chiral nonracemic diols via nucleophilic opening of (S,S)-1,2,3,4-diepoxybutane

    日期:1991.2

  • Modular Asymmetric Synthesis of 1,2-Diols by Single-Pot Allene Diboration/Hydroboration/Cross-Coupling
    作者:Nicholas F. Pelz、James P. Morken
    DOI:10.1021/ol0616891
    日期:2006.9.1
    Chiral allyl vinyl boronates are generated by catalytic enantioselective diboration of prochiral allenes. They may then be reacted, in situ, with a hydroborating reagent to form a novel triboron intermediate. The least hindered and most reactive C-B bond then participates in cross-coupling wherein the coupling is brought about by the same catalyst as that which catalyzed the diboration reaction. The
    手性烯丙基乙烯基硼酸酯是通过前手性烯丙基的催化对映选择性二硼化而生成的。然后可以使它们与硼氢化试剂原位反应以形成新型三硼中间体。然后受阻最少和反应性最强的CB键参与交叉偶联,其中偶联是通过与催化双硼化反应的催化剂相同的催化剂进行的。然后在反应后处理中将剩余的CB键氧化,从而允许以简明的单罐方式模块化合成手性二醇。

  • Use of chiral B(III) complexes in the cycloaddition of C,N-diphenylnitrone to tert-butyl vinyl ether
    作者:Pau Bayón、Pedro de March、Marta Figueredo、Josep Font、Jordi Medrano
    DOI:10.1016/s0957-4166(00)00405-5
    日期:2000.11
    The 1,3-dipolar cycloaddition of C,N-diphenylnitrone to tert-butyl vinyl ether in the presence of several chiral B(III) complexes which incorporate different bidentate ligands has been investigated. The use of these B(III) species reverses the endo/exo diastereoselectivity in relation to the uncatalysed reaction, giving trans cycloadducts as major products. Some of the catalysts gave very fast and high yielding reactions, but the enantioselectivities were only low to moderate. (C) 2000 Elsevier Science Ltd. All rights reserved.

    Several new monoketals of p-benzoquinone with the structure of 1,3-dioxaspiro[4.5]deca-6,9-dien-8-one have been synthesised in enantiopure form by the straightforward reaction of the quinone with secondary C-2-symmetric 1,2-diols.
