    摘要:
    N-(烷氧基)噻唑-2(3H)-硫酮在低吸收性溶剂中的微波辐射(2.45 GHz,300-500 W)提供烷氧基,其通过以下方法鉴定:(i)自旋加合物形成(EPR光谱)和(ii)通过δ-选择性氢原子转移在分子内加成(二取代的四氢呋喃的立体选择性合成),β-片段化(羰基化合物的形成)和脂族亚基的C,H-活化中的指纹类型选择性。由以氧为中心的中间体形成的C自由基被Bu(3)SnH,L-半胱氨酸乙酯,谷胱甘肽的还原形式(还原性俘获)捕获,或通过溴原子供体BrCCl(3)(杂原子功能化)进行研究结果表明,微波活化优于UV / Vis光解法和传导加热,可从N-(烷氧基)噻唑硫酮生成烷氧基自由基。到目前为止,它提供了最短的反应时间,并且可以显着减少捕集试剂的量。

  • On the synthesis of β-bromohydrine ethers via intermolecular alkoxyl radical addition to bicyclo[2.2.1]heptene

    日期:2007.8
    Primary, secondary, and tertiary alkoxyl radicals add exo-selectively to the olefinic π-bond in bicyclo[2.2.1]heptene to afford exo-2-alkoxybicyclo[2.2.1]hept-3-yl radicals, which are trapped with BrCCl3 preferentially from the endo face to furnish β-bromohydrine ethers in 23–67% yield.

  • Aspects of structural thiohydroxamate chemistry—on a systematic in the 5-(p-methoxyphenyl)-4-methylthiazole-2(3H)-thione series
    作者:Jens Hartung、Uwe Bergsträßer、Kristina Daniel、Nina Schneiders、Ingrid Svoboda、Hartmut Fuess

    日期:2009.3
    Bond angles at thiohydroxamate oxygen in crystal structures of 3-alkoxy-5-(p-methoxyphenyl)-4-methylthiazole-2(3H)-thiones gradually increased with the size of the 3-alkoxy substituent. This effect was attributed to strain on the basis of (i) a linear free energy relationship (Taft-Dubois correlation) and (H) signal coalescence from resonances of diastereotopic CH3 groups in solution (O-cumyl substituent; DNMR). Substitution at oxygen along the sequence OR (R prim-, sec-, and tert-alkyl), CH, and OLi was reflected in a gradual decrease of N,O distances and lengthening of associated C,S bonds. The responsivity for these changes was more pronounced in the thiazole-2(3H)-thione than in the pyridine-2(1H)-thione series. (C) 2009 Elsevier Ltd. All rights reserved.

    Methoxyl and isopropoxyl radicals were generated from N-alkoxy-4,5-dimethylthiazole-2(3H)-thiones (λmax∼320 nm) and 5-aryl derivatives (aryl=p-XC6H4; X=MeO, H, AcNH, Cl) (λmax∼335 nm) in photochemically and microwave-induced reactions.
