Abstract:

Six new heptaacetyl maltosyl esters were synthesized. IR and 1H NMR spectra showed that all esters had the same configuration of β-anomer. Alkyl sub
stitutes on benzene showed considerable effects on 1H chemical shifts and 13C chemical shifts of the compounds. The 1H NMR and 13C NMR chemical shifts of the compounds were assigned using both 1D and 2D techniques, including 1H NMR, 13C NMR, 1H-1H COSY, gHMQC and gHMBC.

Key words: NMR, Maltosyl carboxylate, ester,  chemical shift, assignment
