樟脑衍生的手性离子液体的合成及其在不对称环氧化中的应用

The Synthesis of Camphor-derivative Chiral Ionic Liquid and Its Application in Asymmetric Oxidation

以天然樟脑为手性源,设计并合成了一种天然樟脑衍生的手性离子液,并对其结构进行了表征,将该樟脑衍生的手性离子液应用于催化芳醛与苄溴的不对称环氧化,结果表明该新型离子液具有良好的不对称催化性能和循环使用性能,对该类樟脑衍生的手性离子液的分子结构与催化活性的关系还有待于进一步的研究.

With natural camphor as chiral source, a novel structure of Camphor-derivatived chiral ionic liquid was designed and synthesized, and it was applied to the catalytic asymmetric epoxidation of aromatic aldehyde with benzyl bromide. The results showed that this new type of Camphor-derivatived chiral ionic liquid has good asymmetric catalytic and recycling performance. The relationship between molecular structure and catalytic activity of this Camphor-derivatived ionic liquid was discussed.
