    摘要:手性选择性官能化的磁性微球在对映体分离中显示出巨大的潜力.在这项研究中,通过自由基聚合将乙烯基咪唑鎓-β-环糊精氯化物(vimcd-Cl)固定在3-甲基丙烯酰氧基丙基三甲氧基硅烷改性的氧化铁磁性微球上,开发了一类新型的手性磁性选择剂.制备的手性材料具有规则的三维核-壳结构,平均粒径约为580 Nm,高磁化饱和度约为51 Emu G-1.傅立叶变换红外光谱(ft-Ir),热重分析(tga)和元素分析证实了vimcd-Cl在磁性微球表面成功聚合.然后将所制备的功能性磁性材料应用微分批技术应用于三种丹磺酰基氨基酸的选择性手性吸收.结果表明,固定的vimcd-Cl磁性微球(vimcd-Mnps)对三个丹磺酰基氨基酸具有非常好的对映选择性,并且在手性吸附过程中表现出与l-对映体更强的相互作用.此外,这些官能化的手性磁性材料具有优异的可回收性,并且可用作手性分离的有效手性磁性选择剂.

    标题:Mono-and di-derivatives of cyclodextrins, synthesis thereof and purification and use thereof in support
    发明人:DUVAL RAPHAEL; LEVEQUE HUBERT
    权利人:INST FRANCAIS DU PETROLE; CHIRALSEP SARL
    摘要:Mono- and di-derivatives of cyclodextrins are completely defined, also a method for their synthesis and purification, functionalised cyclodextrins obtained from these derivatives, and the synthesis of supports comprising these cyclodextrin derivatives. Use of the supports for the preparation or separation of enantiomers, for asymmetric synthesis, for catalysis, for the preparation or separation of geometrical isomers or positional isomers, or for the preparation or separation of organic molecules with a hydrophobic nature is also described.
