Enantioselective synthesis of β-amino acids. 6. High 1,2-stereoinduction in the preparation of enantiopure 2(R)-hydroxy-3(R)-N-benzoylamino-3-phenylpropionic acid (like stereoisomer of taxol's side chain)

The remarkably high 1,2-stereoinduction encountered in the hydroxylation of 1-benzoyl-3-methyl-6(S)-phenylperhydropyrimidin-4-one [(S)-2] allows for the preparation of enantiopure N-benzoyl (2R,3R)-3-phenylisoserine, the like stereoisomer of taxol's C-13 side chain.
1-苯甲酰基-3-甲基-6(S)-苯基全氢嘧啶-4-酮[ 1]的羟基化过程中遇到的1,2-立体诱导非常高,因此可以制备对映体纯的N-苯甲酰基(2 R,3 R)-3-苯基异丝氨酸,类似于紫杉醇的C-13侧链的立体异构体。
