摘要:

通过对6种七-O-乙酰基-β-麦芽糖基羧酸酯的1H NMR和IR谱的分析, 确证其糖苷键为β-构型, 对其一般特征进行了对比和讨论, 用1H-1H COSY, gHMQC, gHMBC等技术对它们的1H和13C NMR谱峰进行了全归属.

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
