本文报道了12对芳环取代的-α-卤代桂皮酰胺类化合物的UV及~1H NMR。并通过λmax和~1HNMR谱中酰胺氮上的氢及双键β-烯氢的化学位移判断它们的构型,这种判断结果已为X光衍射确证。
In this paper, the UV and ~ 1H NMR spectra of 12 pairs of aromatic ring-substituted α-halogenated cinnamates have been reported. Their configurations were judged by the chemical shifts of the hydrogen on the amide nitrogen and the double bond β-olefin hydrogen in the λmax and ~ 1HNMR spectra. The result of this judgment has been confirmed by X-ray diffraction.
