derivatives was synthesized in order to serve as model compounds for the analysis of the stereochemistry, regiochemistry, and defect structures of poly(vinyl glycoside)s. 13C NMR spectroscopic analysis of these compounds revealed that the attached chiral carbohydrate substituents induced a strong correlation of the chemical shifts of both the anomeric C and the α-C atom of the aglycon with the absolute configuration
合成了一系列糖基化二醇和三醇衍生物,以用作分析聚(乙烯基糖苷)立体化学、区域化学和缺陷结构的模型化合物。这些化合物的 13C NMR 光谱分析表明,连接的手性碳水化合物取代基引起异头 C 和苷元的 α-C 原子的化学位移与后者的绝对构型之间的强相关性。还研究了β-和γ-C原子的立体构型以及苷元的区域化学对α-C和异头C原子的化学位移的影响。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
