Novel anionic reagents for the stereoselective synthesis of γ-hydroxy-α-amino-acids. An X-ray crystallographic study of 2R(S)-benzoylamino-N-t-butyl-4R(S)-hydroxy-4-(4-methoxyphenyl)-3R(S)-methylbutanamide

e2-But)CONHBut, prepared respectively from 4-methoxybenzaldehyde (ArCHO) and the anions MeCHC-(–)C(NBut) and MeCHC(–OSiMe2But)C(NBut), were reduced stereoselectively (25:1) and benzoylated to produce the title amide which was characterized by an X-ray analysis.
