A novel chiral macrocyclic ligand incorporating a chiral salen moiety into a framework containing two biphenyl units was synthesized. Structural properties and conformational aspects of the free ligand and an UO2 complex were studied by using NMR spectroscopy in solution and MM calculations. The Mn(III) complex was tested as catalyst in enantioselective oxidation of prochiral unfunctionalized olefins to the corresponding optically active epoxides under very mild conditions.
合成了一种新型手性大环配体，该配体将手性席夫碱部分引入到含有两个联苯单元的骨架中。通过溶液中的 NMR 光谱和 MM 计算研究了游离配体和 UO2 配合物的结构性质和构象方面。在非常温和的条件下，Mn(III)配合物被测试为手性非官能化烯烃对映选择性氧化为相应的光学活性环氧化物的催化剂。
