Abstract:

Natural abundance N-phosphoryl amino acids were studied by  15N NMR spectroscopy. 15N NMR chemical shifts and coupling constants were determined by 15N-1H heteronuclear HSQC and HMBC techniques. The stereosensitive 1J (15N-31P) and 1J(15N-1H) coupling constants were used to analyze the geometry of nitrogen atoms in these compounds. The structural and 15N NMR spectroscopic characteristics of N-phosphoryl amino acids were discussed.

Key words: NMR,  15N NMR,  2D NMR,  natural abundance N-phosphoryl amino acids
