Chiral bidentate aminophosphinephosphinites (AMPP) ligands bearing different substituents at the aminophosphine and the phosphinite moieties are prepared in a one pot synthesis from aminoalcohols. Their use in asymmetric hydrogenation of activated ketones is described. Upon analysis of these results, it is suggested that the phosphinamido group governs both the activity and the enantioselectivity of
在氨基醇的一锅法合成中制备在氨基膦和次膦酸酯部分带有不同取代基的手性二齿氨基膦次膦酸酯(AMPP)配体。描述了它们在活化酮的不对称氢化中的用途。根据这些结果的分析,建议膦酰胺基控制该反应的活性和对映选择性。
