Abstract

(matrix presented) Samarium(III)-(R)-or (S)-propylenediaminetraacetate complex resovled the enantiomer signals of α-amino acids on high-field ¹H and ¹³C NMR with remarkably less line broadening than was previously reported for the Eu(III) complex of the same ligand. A widely observed regularity between the absolute configuration of enantiomers and the relative shift of their NMR signal is useful for the assignment of absolute configuration.
