1,2,3,4,6-Penta-O-acetyl-alpha-D-glucopyranose and the corresponding [1-(2)H], [2-(2)H], [3-(2)H], [4-(2)H], [5-(2)H], and [6,6-(2)H(2)]-labeled compounds were prepared for measuring deuterium/hydrogen-induced effects on (13)C chemical shift (n)Delta (DHIECS) values. A conformational analysis of the nondeuterated compound was achieved using density functional theory (DFT) molecular models that allowed
1,2,3,4,6-五-O-乙酰基-α-D-吡喃葡萄糖和相应的[1-(2)H],[2-(2)H],[3-(2)H] ,[4-(2)H],[5-(2)H]和[6,6-(2)H(2)]标记的化合物用于测量氘/氢对(13)的影响C化学位移(n)Delta(DHIECS)值。使用密度泛函理论(DFT)分子模型对非氘代化合物进行了构象分析,该模型可以通过使用包括轨距的原子轨道方法计算几种结构性质以及Boltzmann平均(13)C NMR化学位移。发现DFT计算的CH键长度与(1)Delta DHIECS相关。
