A reliable and convenient method for determining the configuration and conformation of the furanose ring in carbohydrates and nucleosides by vibrational circular dichroism (VCD) spectroscopy is described. Diastereomeric pairs of several furanose monosaccharides and nucleosides were prepared, and their VCD spectra were analyzed. The results revealed that VCD spectroscopy elucidates the equibrated state of the furanose ring puckers, which is often difficult to study by other techniques.
本文描述了一种通过振动圆二色性（VCD）光谱法测定碳水化合物和核苷中环呋喃糖的构型和构象的可靠、便捷方法。本文制备了几对非对映异构体的呋喃单糖和核苷，并对它们的 VCD 光谱进行了分析。结果表明，VCD 光谱法阐明了呋喃糖环褶皱的平衡态，这通常很难用其他技术进行研究。
