英文摘要The acetyl, sulfonyl and phosphoryl are three amino protecting groups. The natural abundance N-15-NMR of their derivatives of the phenylethylglycine and beta-phenylethylamine has been studied. We found that there are great difference in the chemical shifts of the three protected compounds, delta N-15 is shifted to upfield in turn. Among these three amino protecting groups, the diisopropoxyphosphinyl one produces the least deshielding effect, while the acetyl group gives the strongest deshielding effect, and the tosyl group is in the middle. The trend of deshieding effect of the three protecting groups occured also in the H-1 NMR (Table 1). Furthermore, we have studied the relation of chemical shifts to the atomic charge and molecular structures by means of semiempirical molecular orbital CNDO/2 and X-ray diffraction of single crystal structure analysis.
