NMR spectra of some N-(tetra-o-acetyl-β-dglycopyranosyl)thiosemicarbazones from natural carbonyl compounds

The thiosemicarbazone of N- (tetra-O-acetyl-β-D-glycopyranosyl) of some naturally derived aldehydes and ketones has been synthesized and studied in the MNMR spectrum. The 1H and 13C NMR spectra of these thiosemicarbazon were discussed. Magnetic resonance signals in their NMR spectrum indicate the relationship between the structure and the position of the resonant signal. The configuration β of these thiosemicarbazon is confirmed based on the pairing constant J = 9.5–8.5 Hz between the NH-4 proton of the thiosemicarbazon proton and the H-1 proton in the sugar component.
