Suitable protected derivatives of trihydroxynorleucines-[(2S,4S,5S)- and (2R,4S,5S)-2-amino-4,5,6-trihydroxyhexanoic acid,] of all isomeric dihydroxynorvalines [2-amino-4,5-dihydroxypentanoic acids), of all isomeric 2-amino-6,7-dihydroxyheptanoic acids and of (2S)-2-amino-6-hydroxymethyl-7-hydroxyheptanoic acid are synthesized via the corresponding α,β-didehydro compounds, which are hydrogenated with the optically active homogeneous catalyst [Rh(COD)(DIPAMP)]+ BF- 4.
(2S,4S,5S)-和(2R,4S,5S)-2-氨基-4,5,6-三羟基己酸、]所有异构体二羟基缬氨酸[2-氨基-4,5-二羟基戊酸]、所有异构体2-氨基-6、7-二羟基庚酸和 (2S)-2- 氨基-6-羟甲基-7-羟基庚酸是通过相应的 δ、δ²-二氢化物合成的,这些化合物在光学活性均相催化剂[Rh(COD)(DIPAMP)]+ BF- 4 的作用下进行氢化。
