A general strategy for the stereochemical analysis of 1-carboxyethyl sugar ethers is introduced in which the chirality of the lactyl group is related to that of the sugar moiety in a conformationally rigid lactone derivative. With the aid of molecular modeling, the stereochemistry is determined through the use of NOE measurements. This procedure was evaluated using synthetic diastereomeric samples
介绍了 1-羧乙基糖醚立体化学分析的一般策略,其中乳基的手性与构象刚性内酯衍生物中糖部分的手性有关。在分子建模的帮助下,立体化学是通过使用 NOE 测量来确定的。该程序使用 (R)- 和 (S)-甲基 3-O-(1-羧乙基)-α-L-吡喃鼠李糖苷的合成非对映体样品进行评估,并成功应用于 N-乙酰胞壁酸的立体化学分析
