    Zur Stereochemie einiger neuer chiraler Bromverbindungen mit einem 2,4,8,10-Tetraoxaspiro[5.5]-undecan ? Ger�st
    摘要:
    New compounds containing the 2,4,8,10-tetraoxaspiro[5.5] undecanic skeleton, substituted with brominated groups, have been synthesized by a regioselective radicalic bromination reaction. The stereochemistry of the compounds was studied by high resolution NMR methods. The anancomericity or the flipping of the rings was inferred from the conformational analysis. The chirality of the spiranic skeleton was investigated by means of the diastereotopicity of hydrogen and carbon atoms.

  • A Facile, Selective Preparation of Monoketals from Pentaerythritol and Ketones
    作者:Ricardo Grau、Marcelo Murguía、Santiago Vaillard

    The selective preparation of monoketals 3a-f from pentaerythritol 1 and cyclic, acyclic, aromatic, and aliphatic ketones 2a-f was achieved by a facile method. The extreme polarity and low solubility of pentaerythritol in almost all organic solvents were the main difficulties to be overcome for the preparation of monoketals in good yields and high selectivity. A benzene-dimethylformamide (40:60) mixture proved to be excellent for the ketalization. The one-step procedure developed allowed the preparation of monoketals in good yields and good to excellent selectivity (higher than 90%).
    通过一种简便的方法成功地从五羟基醇1和环状、非环状、芳香族和脂肪2a-f选择性制备了单基化合物3a-f。五羟基醇在几乎所有有机溶剂中的极高极性和低溶解度是制备单基化合物时主要需要克服的困难。实验表明,-二甲基酰胺(40:60)混合物在基化反应中表现优异。所开发的一步法程序使得单基化合物的制备在良好收率和良好至优异选择性(超过90%)下得以实现。
