(S)- and (R)-2,2′-Bis[bis(3,5-dimethylphenyl)phosphinoyl]-5,5′,6,6′,7,7′,8,8′-octahydro-1,1′-binaphthyl (Xyl-H8-BINAPO) were synthesised by reacting chlorobis(3,5-dimethylphenyl)phosphine with (S)- and (R)-2,2′-dihydroxyl-5,5′,6,6′,7,7′,8,8′-octahydro-1,1′-binaphthyl, respectively. The applications of these ligands and their corresponding parent analogues in the Rh-catalysed asymmetric hydrogenation
(S)-和(R)-2,2'-双[双(3,5-二甲基苯基)膦酰基] -5,5',6,6',7,7',8,8'-八氢-1通过使氯双(3,5-二甲基苯基)膦与(S)-和(R)-2,2'-二羟基-5,5',6,反应合成1,1'-联萘基(Xyl-H 8 -BINAPO), 6',7,7',8,8'-八氢-1,1'-联萘基。这些配体及其相应的母体类似物在Rh催化的各种乙酰氨基丙烯酸和酯的不对称加氢中的应用为手性氨基酸衍生物提供了良好或优异的ee(高达97%)。
