| titleOfInvention | DETERMINATION BY NUCLEAR MAGNETIC RESONANCE OF THE ABSOLUTE CONFIGURATION OF AMINO ACIDS OR THEIR DERIVATIVES AND METAL COMPLEXES OF CHIRAL PORPHYRINS USABLE FOR THIS DETERMINATION |
| abstract | The invention relates to novel metal complexes of chiral porphyrins of formula (I) capable of binding to an axial coordination site an alpha-amino acid or a derivative thereof carrying an asymmetric carbon, and of acting thus the role of chiral chemical shifting agent. Complexation in the vicinity of porphyrin causes high-field displacement of alpha-amino acid proton NMR signals, as well as changes in some porphyrin proton NMR signals. These shifts are characteristic of the R or S configuration of asymmetric carbon. Examination of the 1 H NMR spectrum thus constitutes an easy means for determining the absolute configuration of the alpha-amino acid or derivative, as well as for detecting the racemization of these compounds. |
