  Influence of the stereochemistry of sugars on the selectivity of formation of carbohydrate-derived cyclopentadienyl and indenyl ligands

  摘要：

  环戊二烯锂与适当的部分受保护的 α-D-allofuranose triflate（4，葡萄糖 C3 的缩合物）相互作用，除了得到预期的葡萄糖-环戊二烯（5）外，还得到葡萄糖-二取代环戊二烯（6）作为主要产物。α-D-呋喃葡萄糖和其他糖类不会出现这种前所未有的现象，初步解释是 LiCp 与 4 和 5 分子中一个分子的异亚丙基官能团的氧原子发生了络合反应，从而产生了作为模板效应结果的三分子结构。其他实验的结果，如使用 MgCp2 代替 LiCp 或用三酸锂络合氧原子，在很大程度上改变了反应的选择性，有利于单取代产物 5，也支持了这一假设。当茚化锂与 4 反应时，分别生成葡萄糖一取代茚和葡萄糖二取代茚，即 8 和 9，并以几乎完全的非对映选择性得到 9。这一结果也可以通过锂的立体选择性络合得到合理解释，正如单独的实验和分子力学计算所显示的那样。以葡萄糖一取代的 5 环戊二烯和葡萄糖二取代的 6 环戊二烯为原料，合成了甲基三羰基钼（II）配合物，并对其进行了表征。
