| 摘 要： | 手性多酸的合成是多酸化学研究领域中一个难度很高的挑战性课题, 也是近年的研 究热点之一, 从本质上来说， 其关键的工作是进行多酸分子的构建. 作者研究小组运用自 主发展的DCC 亚胺化方法, 将把刚性的多酸有机衍生物通过碳-碳或碳-氮单键组装起来, 这样的组装体系就有可能因单键旋转受阻形成轴手性分子; 在多酸簇上接上一个长的非 平面手柄, 从而形成手性“环蕃”. 本文报道了通过以上合成策略, 以高度可控方式合成新 型多酸有机衍生物, 并构建多酸手性分子的最新进展.

| Abstract: | The synthesis of chiral polyoxometalates (POMs) has attracted increasing attention in recent years. The aim of this research was to construct different rigid POMs with organic derivatives. The POMs were synthesized with C–C or C–N links using N,N'-dicyclohexylcarbodiimide (DCC) protocol. The synthesized POMs are probably chiral because of increased steric hindrance of the bulky POMs to rotation at the C–N or C–C bond. Novel diorganoimido-substituted POM-based chiral macrocycles were synthesized using the DCC protocol. The POM macrocycles were produced in a controllable manner from achiral Lindqvist hexamolybdate and bis aryl amines bearing o-alkoxy chain substituents. Recent advances in synthesis of chiral POMs based on organoimido-substituted POMs are reviewed. |
