corresponding chiral 2,3-disubstituted-1-indanols 2 by ruthenium(II)-catalyzed dynamic kinetic resolution–asymmetric transfer hydrogenation. In particular, this route offers a practical access to a new class of conformationally rigid enantiopure 1,4-diols 2k–m having four contiguous chiral centers. Transformation of ent-2k into a Pallidol analogue via a highly diastereo- and regioselective Friedel–Crafts
具有两个立体不稳定中心的活化的外消旋2,3-二取代的1-茚满酮1通过钌(II)催化的动态动力学拆分-不对称转移氢化反应被立体选择性地还原为相应的手性2,3-二取代的-1-茚满醇2。特别地,该途径为获得具有四个连续手性中心的新型构象刚性对映纯1,4-二醇2k - m提供了实用途径。介绍了通过高度非对映体和区域选择性的Friedel-Crafts邻氯苯甲醚苄基化反应将ent - 2k转化为Pallidol类似物的过程。
