Active and selective catalysts for the asymmetric reduction of ketones, under transfer hydrogenation conditions, were obtained by combining [RhCl2Cp*]2, with a series of L-amino acid thioamide ligands functionalized with 1,2,3-triazoles. The obtained secondary alcohol products were formed with up to 93% ee.
通过转移加氢条件获得了用于酮不对称还原的活性和选择性催化剂。 [RhCl 2 Cp *] 2,带有一系列 L-氨基酸硫代酰胺1,2,3-三唑官能化的配体。所形成的仲醇产物具有高达93%的ee。
