NMR Studies on Glycosyl Guanidines Containing Arylthiazol
含芳基噻唑糖基胍的NMR研究

Four new tetraacetyl galactosylguanidines were synthesized and characterized by NMR spectroscopy. The ^1H and ^13C NMR chemical shifts of these compounds were assigned using both 1D and 2D techniques, including ^1H NMR, ^13C NMR,^1H-^1H COSY, gHMQC, gHMBC and NOESY. The NMR data showed that all galactosyl had the same configuration of fl-anomer. The spectral characteristics of the compounds were analyzed and compared.
