We have developed a family of Ir–P,oxazoline catalysts for asymmetric hydrogenation. These catalysts, with a simple modular architecture, have shown a high tolerance to the olefin geometry and substitution pattern, and to the presence of several neighboring polar groups. Thus, they were able to successfully hydrogenate disubstituted, trisubstituted, and tetrasubstituted minimally functionalized olefins (with enantiomeric excess values up to 99%). The excellent catalytic performance was also extended to the hydrogenation of cyclic β-enamides.

易获得的Ir-P，恶唑啉催化剂对二取代，三取代和四取代的最小官能化烯烃和环状β-酰胺的不对称加氢反应

我们已经开发了用于不对称氢化的Ir-P，恶唑啉催化剂系列。这些具有简单模块化结构的催化剂对烯烃的几何形状和取代模式以及几个相邻的极性基团的存在表现出很高的耐受性。因此，他们能够成功地氢化二取代，三取代和四取代的最小官能化烯烃（对映体过量值最高可达99％）。优异的催化性能还扩展到环状β-烯酰胺的氢化反应。
