    Cycloaddition reactions on activated exo-glycals
    摘要:
    Cycloaddition reactions of activated exo-glycals and nitrones proceeded only under microwave activation, with excellent facial selectivities on furanoglycosylidenes and good stereocontrol on the nitrone producing only two diastereomeric spiroisoxazolidines. alpha/beta-Spiro sugar-isoxazolidines are obtained from pyrano exo-glycals. The cycloaddition reaction with nitrile oxide proceeds at room temperature and gives open-chain isoxazoles due to facile beta-elimination of the sugar ring oxygen on the intermediate isoxazoline ring system. All the heterocycles obtained this way can be regarded as nucleoside analogues. (C) 2005 Elsevier Ltd. All rights reserved.

  • A Novel Nitrone Cycloaddition/Rearrangement
    作者:Bruce H. Toder、George B. Mullen、Vassil St. Georgiev
    DOI:10.1002/hlca.19900730119
    日期:1990.1.31
    Adamantanone-derived nitrone 4 and some other keto-nitrones, when reacted with aromatic and aliphatic aldehydes in refluxing toluene or tetrahydrofuran, formed the corresponding aldonitrones (Z)-10, the latter arising from the fragmentation of an initially formed 1,4,2-dioxazolidine 6 to adamantan-2-one and an oxaziridine intermediate 11, which then rearranges to (Z)-10.
    金刚烷酮衍生的硝酮4和其他一些酮-硝酮,当与芳族和脂族醛在回流的甲苯或四氢呋喃中反应,形成相应的aldonitrones(ż) - 10,后者从初始形成的碎片而产生1,4,2 -二恶唑烷6至金刚烷-2-酮和恶唑烷中间体11,然后将其重排为(Z)-10。
  • Lipase-catalyzed asymmetric synthesis of oxathiazinanones through dynamic covalent kinetic resolution
    作者:Lei Hu、Yan Zhang、Olof Ramström
    DOI:10.1039/c4ob00365a
    日期:——
    A domino addition–lactonization pathway has been applied to a dynamic covalent resolution protocol, leading to efficient oxathiazinanone formation as well as chiral discrimination. A new, double biocatalytic pathway has furthermore been proposed and evaluated where the initial product inhibition could be efficiently circumvented.

  • Organocatalysts Promote Enantioselective 1,3-Dipolar Cycloadditions of Nitrones with 1-Cycloalkene-1-carboxaldehydes
    作者:Staffan Karlsson、Hans-Erik Högberg
    DOI:10.1002/ejoc.200300172
    日期:2003.8
    In the presence of enantiopure organocatalysts, 1-cycloalkene-1-carboxaldehydes and various nitrones furnished fused isoxazolidines. Thus, some chiral pyrrolidinium salts catalyzed the formation of such cycloadducts in high diastereo- and enantioselectivity (up to 92% ee). The predominant diastereomer, the exo one, was mostly obtained in excellent diastereoselectivity (> 99:1 dr). Furthermore, after
    在对映体纯有机催化剂存在下,1-环烯烃-1-甲醛和各种硝酮提供稠合异恶唑烷。因此,一些手性吡咯烷盐以高非对映选择性和对映选择性(高达 92% ee)催化此类环加合物的形成。主要的非对映异构体,即外向异构体,主要以优异的非对映选择性 (> 99:1 dr) 获得。此外,在环加合物之一重结晶后,得到对映体纯(> 99% ee)。确定环加合物之一的绝对构型。
  • A new, stereoselective approach to pyrrolidine-N-oxides by sequential condensation of sulfones with nitrones and reverse-cope elimination
    作者:Andrew R. Wheildon、David W. Knight、Mathew P. Leese
    DOI:10.1016/s0040-4039(97)10245-3
    日期:1997.12
    Lithiosulfones 10 condense smoothly and highly stereoselectively with nitrones 11 to give unsaturated hydroxylamines 12 which undergo reverse-Cope cyclisations at varying rates leading to pyrrolidine-N-oxidies 13 and 14; the former isomerized slowly to diastereoisomers 20.

    13C MAS nuclear magnetic resonance experiments. We have also studied the temperature profile during the reaction. A comparative study with the corresponding solvent-free microwave activated reaction showed the superiority of the ball-milling method; 31 examples are described, including the synthesis of the anti-aging agent C-phenyl-N-tert-butyl nitrone (PBN) and one of its analogues C-2-pyridyl-N-tert-butylnitrone
