摘要: 本文报道了24个α被13种基团取代的桂皮酰胺类化合物的1H NMR和UV数据.用经验公式计算了β-H的化学位移.结果表明,其测定值与计算值的比较可用于推断这类化合物的顺反构型.它们苯基上质子的化学位移也可为判断构型提供依据.对于成对的化合物,酰胺氮上质子的化学位移及紫外光谱亦有助于判断构型.

Abstract: The 1H NMR and UV spectral data of 24 cinnamamides whose α-position was substituted with 13 types of groups are reported. The chemical shifts of β-H were calculated with empirical equation. The result shows that comparison of experimental values with calculated values can be used for concluding cis-or trans-configuration of these compounds. The chemical shifts of phenyl pretons can also give evidence for configuration. For the pairs of these compounds, the chemical shifts of protons on amide nitrogen and the UV spectra arc helpful for assigning configuration.
