Natural Abundance N-Phosphoryl Amino Acids Studied by 15N NMR Spectroscopy
天然丰度的N-磷酰化氨基酸的15N NMR 研究

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.
