  Asymmetric Epoxidation Catalyzed by N-Aryl-Substituted Oxazolidinone-Containing Ketones:  Further Evidence for Electronic Effects

  摘要：

  [GRAPHICS]Ketones containing N-aryl-substituted oxazolidinones have been prepared and investigated for the epoxidation of cis-beta-methylstyrene, styrene, and 1-phenylcyclohexene. The attractive interaction between the phenyl group of the olefin and the oxazolidinone of the catalyst is enhanced by introducing an electron-withdrawing group onto the N-phenyl group of the catalyst. The information obtained gives a better understanding of the ketone-catalyzed epoxidation. In addition, the easy preparation of some of the ketones makes them good candidates for practical use.

• Highly Enantioselective CH Oxidation of <i>v</i><i>ic</i>-Diols with Shi's Oxazolidinone Dioxiranes

  日期：2006.7.1

  [reaction: see text] Through an analogical study of the transition states of CH oxidation and asymmetric epoxidation of terminal alkenes, the first dioxirane-mediated catalytic highly enantioselective CH oxidation method was realized with Shi's oxazolidinone ketone derivatives. Very good enantioselectivity (up to 92% ee) may be obtained for both asymmetrization of meso vic-diols and kinetic resolution

  [反应：参见正文]通过对CH氧化和末端烯烃不对称环氧化的过渡态的类似研究，使用Shi的恶唑烷酮酮衍生物实现了第一个二环氧乙烷烷介导的催化高对映选择性CH氧化方法。对于内消旋vic-二醇的不对称化和外消旋vic-二醇的动力学拆分，可以获得非常好的对映选择性（高达92％ee）。
