    摘要:
    作为我们开发新型抗疟疾工作的一部分,我们对拟定一种合适的合成策略以制备含内过氧化物的桥连双环支架感兴趣。通过TMSOTf促进脱水环化策略,我们合成了2,3,8-三氧杂双环[3,3,1]壬烷过氧化物。通过暴露于格氏试剂可容易地引入双环支架的C4处的烷基取代基。

  • Direct Synthesis of Spiro .delta.-lactones, Spiro-.gamma.-Lactones, and Alcohols from Substituted (2-Butene-1,4-diyl)magnesium Complexes
    作者:Reuben D. Rieke、Matthew S. Sell、Heping Xiong
    DOI:10.1021/jo00121a036
    日期:1995.8
    A convenient, one-pot process for the synthesis of spiro delta- and gamma-lactones and alcohols from conjugated dienes mediated by Rieke magnesium is described. This technique involves the treatment of a substituted (2-butene-1,4-diyl)magnesium complex with an epoxide or ketone at -78 degrees C, followed by the addition of carbon dioxide at 0 degrees C to room temperature. After acidic hydrolysis and subsequent warming, a spiro delta- or gamma-lactone accommodating both a quaternary carbon center and vinyl moiety at the beta-position is afforded in good isolated yield. Alternatively, acidic hydrolysis of the initially formed adduct at 0 degrees C furnishes an alcohol containing a quaternary carbon center in good to excellent chemical yield.
  • A synthetic strategy to bridged 2,3,8-trioxabicyclo[3,3,1]nonane endoperoxides

    appropriate synthetic strategy for the preparation of endoperoxide-containing bridged bicyclic scaffolds. Through a TMSOTf-promoted dehydrative cyclization strategy we synthesized 2,3,8-trioxabicyclo[3,3,1]nonane endoperoxides. Alkyl substituents at C4 of the bicyclic scaffold could be readily introduced through exposure to Grignard reagents.
