High-throughput screening considering a library of 96 chiral P-ligands involved in two types of Rh(I) complexes was used for the identification of homogeneous catalysts for the highly enantioselective reductive amination of alpha-keto acids with benzylamine. After optimization of the reaction conditions and scale-up with a cationic Rh-Deguphos catalyst, a range of chiral alpha-amino acids could be produced by this new reaction in good yield and by up to 98% ee.
通过高通量筛选,研究了96种参与两种铑(I)配合物的手性磷配体库,用于鉴定α-酮酸与苄胺的高对映选择性还原胺化反应的均相催化剂。在用阳离子铑-德古磷催化剂优化反应条件并放大规模后,通过这种新反应可以以良好的产率和高达98%的对映体过量(ee)制备一系列手性α-氨基酸。
