The first example of asymmetrichydrogenation of imines using Co2(CO)8/(R)-BINAP/H2/CO system was developed. The reaction conditions were screened with a wide range of N-aryl benzophenone ketimines, obtaining products with excellent yields and good enantiomeric excess. Moreover, a pathway is suggested based on the isolation and characterization of several catalyst intermediates.
开发了使用Co 2(CO)8 /(R)-BINAP / H 2 / CO系统进行亚胺不对称氢化的第一个例子。用各种N-芳基二苯甲酮酮亚胺筛选反应条件,得到具有优异产率和良好对映体过量的产物。此外,基于几种催化剂中间体的分离和表征,提出了一种途径。
