Asymmetric synthesis of organoelemental analogs of natural compounds. 7. (2R,3S)-2-amino-3-hydroxy-5-phosphonovaleric acid

The reaction of the Ni(II) complex of the Schiff base of glycine with (S)-2-N-(N¹-benzylprolyl)-o-aminobenzophenone with diethyl-3-bromo-2-hydroxypropyl phosphonate yields the corresponding complex from which (2R, 3S)-2-amino-3-hydroxy-5-phosphonovaleric acid is separated with HCl.See 1] for Communication 6.Institute of Bioorganic Chemistry and Petrochemistry, Ukrainian Academy of Sciences, 252660 Kiev; N.
