readily preparable chiral diamines were obtained new aminophosphines, (3S)-[N,N′-bis(diphenylphosphino)]-3-aminopiperidine, and (3S)-[N,N′-bis(diphenylphosphino)]-3-(methylamino)piperidine. Asymmetric hydrogenation of α-acylaminoacrylic acids, employing Rh(I) complexes with these aminophosphines as catalyst, gave optically active N-acyl-α-amino acids.
从容易制备的手性二胺中获得了新的氨基膦、(3S)-[N,N'-双(二苯基膦)]-3-氨基哌啶和(3S)-[N,N'-双(二苯基膦)]-3-(甲氨基)哌啶。α-酰基氨基丙烯酸的不对称氢化,使用 Rh(I) 配合物与这些氨基膦作为催化剂,得到光学活性的 N-酰基-α-氨基酸。
