We describe here a manganese-catalyzed asymmetric transfer hydrogenation of hindered ketones containing 2,6-disubstituted phenyl group. This method is enabled by using a readily available chiral aminobenzimidazole manganese(I) complex as the catalyst in combination with ammonia borane compounds as the hydrogen source (especially, dimethylamine borane), producing the chiral alcohols with up to 99 %
我们在这里描述了含2,6-二取代苯基的受阻酮的锰催化不对称转移氢化。该方法通过使用容易获得的手性氨基苯并咪唑锰(I)配合物作为催化剂,结合氨硼烷化合物作为氢源(特别是二甲胺硼烷),生产出手性醇,其收率高达99%,收率令人满意。重要的是,2,6-二取代二苯甲酮可以顺利转化为目标产物,其ee高达95%,收率令人满意。
