Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 40:1692-1699
A convenient method is proposed for the preparative synthesis of pure diastereomers and enantiomers of fluoro-substituted (2S,3R)- and (2R,3R)-β-phenylserines by the hydroxyalkylation of the Ni(II) — complex of the Schiff base of glycine with (S)-

Asymmetric synthesis of heteroorganic analogs of natural compounds. 3. General preparative method of diastereo- and enantioselective synthesis of fluorine-containing 2(R), 3(S)-?-phenylserines
Autor: Yu. N. Belokon, Alexander B. Rozhenko, Valery P. Kukhar, Vadim A. Soloshonok, M. T. Kolycheva, S. V. Galushko
Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 40:1046-1054
The diastereo- and enantioselective synthesis of the previously unknown 2(R), 3(S)-Β-phenylserines containing fluorine atoms, the O-CHF2-, O-CF3-, and CF3 groups in the benzene ring, was carried out by alkylation of a Ni(II) complex of a Schiff base
