A novel chiral surfactant-type catalyst is developed. Micelles formed in water by association of the catalysts themselves, and this was confirmed by TEM analyses. Asymmetric transfer hydrogenation of aliphaticketones catalyzed by the chiral metallomicellar catalyst gave good to excellent conversions and remarkable stereoselectivities (up to 95% ee). Synergistic effects between the metal-catalyzed
开发了一种新型手性表面活性剂型催化剂。通过催化剂本身的结合在水中形成胶束,这通过 TEM 分析得到证实。由手性金属胶束催化剂催化的脂肪族酮的不对称转移氢化具有良好到优异的转化率和显着的立体选择性(高达 95% ee)。金属催化中心与金属胶束中核心的疏水微环境之间的协同作用导致高对映选择性。
