New chiral derivatizing agents: Convenient determination of absolute configurations of free amino acids By 1H NMR
The chiral carbonate reagents 5 allow for the direct and unambiguous determination of the absolute configurations of a wide range of free amino acids using 1H NMR. By using a ~3:1 mixture of (S)-5 and (R)-5, absolute configurations of the corresponding carbamates are determined by only analyzing the nitrogen protons.
