  通过偶联钌和酶催化的二级二醇的动态动力学拆分。

  摘要：

  二级对称二醇的酶促酰化（作为 meso/dl 混合物）与钌催化的二醇异构化相结合，导致有效的动态动力学拆分。通过这种方式，二醇的内消旋/dl 混合物转化为对映异构纯的 (R,R)-二乙酸酯，从而有效利用所有二醇材料。对于一些柔性基材，大量的内消旋二乙酸盐作为副产物形成。结果表明，内消旋产物的主要部分是通过分子内酰基转移途径形成的。

• Efficient and Chemoselective Reduction of Pyridines to Tetrahydropyridines and Piperidines<i>via</i>Rhodium-Catalyzed Transfer Hydrogenation

  日期：2013.1.14

  [Cp*RhCl2]2, catalyzes efficiently the transfer hydrogenation of various quaternary pyridinium salts under mild conditions, affording not only piperidines but also 1,2,3,6‐tetrahydropyridines in a highly chemoselective fashion, depending on the substitution pattern at the pyridinium ring. The reduction is conducted in azeotropic formic acid/triethylamine (HCOOH‐Et3N) mixture at 40 °C, with catalyst loadings

  在碘化物阴离子的作用下，铑络合物二聚体[Cp * RhCl 2 ] 2在温和的条件下有效催化各种季铵盐的转移氢化，不仅提供哌啶，而且还提供高度化学选择性的1,2,3,6-四氢吡啶取决于吡啶环上的取代方式。还原反应是在40°C的共沸甲酸/三乙胺（HCOOH-Et 3 N）混合物中进行的，催化剂负载量低至0.005 mol％是可行的。

  日期：2022.3

  The development of the frustrated Lewis pair catalyzed hydrogenation of tertiary and secondary amides is reviewed. Detailed insight into our strategies in order to overcome challenges during the reaction development process is provided. Furthermore, the developed chemistry is extended to the hydrogenation of polyamides and of trifluoroacetamides for the convenient introduction of trifluoroethyl groups into organic molecules.

• Diastereoselective synthesis of 2,5-dimethylpyrrolidines and 2,6-dimethylpiperidines by reductive amination of 2,5-hexanedione and 2,6-heptanedione with hydride reagents

  DOI：10.1016/s0040-4020(01)85010-9

  日期：1994.4

  The reductive amination of 2,5-hexanedione and 2,6-heptanedione with ammonia and primary amines in the presence of hydride reagents afforded 2,5-dimethylpyrrolidines and 2,6-dimethylpiperidines with variable diastereoselectivity, as the cis/trans ratio was affected by the size of the ring formed and the steric and electronic properties of the nitrogen substituent. Increasing the bulkiness of the nitrogen substituent, the cis pyrrolidines and the bans-piperidines were obtained with enhanced selectivity.
