  Managing Highly Coordinative Substrates in Asymmetric Catalysis: A Catalytic Asymmetric Amination with a Lanthanum-Based Ternary Catalyst

  摘要：

  Full details of a catalytic asymmetric amination with a lanthanum/amide-based ligand catalyst system are described. A catalyst comprising La(NO3)(3)center dot 6H(2)O, (R)-3a and H-D-Val-V'Bu was identified to promote the catalytic asymmetric amination of nonprotected succinimide derivative 1 with as little as 1 mol % catalyst loading Mechanistic studies by various spectroscopic analyses and several control and kinetic experiments suggested that the catalyst components were in equilibrium between the associated and dissociated forms, and that the reaction likely proceeded through a La(NO3)(3)center dot 6H(2)O/(R)-3a/H-D-Val-O'Bu ternary complex. This catalyst system was also effective for asymmetric amination of N-nonsubstituted alpha-alkoxycarbonyl amides 7, hitherto unprecedented substrates in asymmetric catalysis, probably due to their attenuated reactivity and difficult stereocontrol, affording the amination products in up to > 99% yield and > 99% ee. The high catalytic performance and enantiocontrol of the reaction with highly coordinative substrates were achieved by the activation/recognition of the substrates exerted by coordination to lanthanum and hydrogen bonding cooperatively in the transition state.

  摘要：

  已经开发了使用丙酮氰醇作为氰化氢（HCN）源的Cu催化α-芳基重氮酸酯氢氰化的方法。已经发现，添加三甲基甲硅烷基氰化物（TMSCN）可以通过原位释放游离氰离子来显着加速转化，从而在温和条件下以高收率生产各种类型的α-芳基氰乙酸酯。
