Michael addition of octafluoropentyl vinylsulfonate to complexes of Ni
(II) with Schiff's bases derived from S-2-N-(N-benzylprolyl)-o-aminobe
nzophenone and glycine or S-2-N-(N-benzylprolyl)-o-aminobenzaldehyde a
nd alanine is a convenient preparative method for asymmetric synthesis
of previously unknown fluorinated esters of S-homocysteic acid.
