    甲硅烷氧基炔烃通过扩环合成中型内酯
    摘要:
    由于不利的动力学和热力学特征,中环内酯的合成仍然是有机合成中的挑战性课题。在本文中,我们详细介绍了一种有效的分子间过程,该过程使用甲硅烷氧基炔烃作为底物,以氧杂环丁烷环扩环为关键策略。通过扩展到新的甲硅烷基掩盖的炔烃,该反应现在具有广泛的范围,高效和温和的条件。

  • A New Strategy for Efficient Synthesis of Medium and Large Ring Lactones without High Dilution or Slow Addition
    作者:Wanxiang Zhao、Zigang Li、Jianwei Sun
    DOI:10.1021/ja400883q
    日期:2013.3.27
    We have developed an efficient method for medium and large ring lactone synthesis by a conceptually different ring-expansion strategy. The design of an unprecedented ring conjunction mode of oxetene, combined with the appropriate choice of a Lewis acid promoter and an additive, constitutes the key components of the new process. Enabled by this new approach, the reaction does not require high dilution
    我们通过概念上不同的扩环策略开发了一种有效的中环和大环内酯合成方法。The design of an unprecedented ring conjunction mode of oxetene, combined with the appropriate choice of a Lewis acid promoter and an additive, constitutes the key components of the new process. 通过这种新方法,反应不需要高度稀释或缓慢添加。

  • Cooperative effect of the camphor imine ligand in alkynols activation by trans-[MCl2(YNC10H14O)2] (M=Pd or Pt)
    作者:M. Fernanda N.N. Carvalho、Ana S.D. Ferreira、Adelino M. Galvão
    DOI:10.1016/j.ica.2010.03.006
    日期:2010.5
    The cooperative effect of the camphor imine ligand (YNC10H14O) in the cyclization of 5-hexyn-1-ol and 4-pentyn-1-ol promoted by complexes trans-[MCl2(YNC10H14O)(2)] (M = Pd, Y = NH2, NHMe, NMe2, OH, Ph; Pt, Y = NH2, NHMe, NMe2) is established from a direct relation between the constants calculated for conversion of 5-hexyn-1-ol (A) into 2-methyl-2-pent-4-ynyloxy-tetrahydropyran (B) and 4-pentyn-1-ol (C) into 2-methyl-2-pent-4-ynyloxy-tetrahydrofuran (D) and the basic character of the camphor imine substituent (Y). In the catalytic process acid-base interactions between the alkynol and the coordinated camphor imine are supported by the structural characterization of [PdCl4][Me2NHNC10H14O](2).
