Abstract
Difunctionalization of D-isomannide yielded a bis(bipyridine) ligand bearing four stereogenic centers whose diastereoselective self-assembly to enantiomerically pure dinuclear helicates upon coordination to different metal ions was investigated by NMR and CD spectroscopic as well as ESI mass spectrometric methods.
摘要
D-异甘露糖醇的双官能化反应生成了一种带有四个手性中心的双（联吡啶）配体，通过核磁共振、圆二色光谱以及电喷雾质谱法研究了该配体在与不同金属离子配位时非对映选择性自组装形成对映体纯双核螺旋配合物的情况。
