The highly stereoselective α(1→4) coupling between two d-galacturonic acid ester derivatives was accomplished in good yields, for the first time, using a phenylthioglycoside as donor. The method was designed to prepare d-galacturonic acid oligomers with methyl ester groups in definite positions.
使用苯硫代糖苷作为供体,首次以高收率实现了两个d-半乳糖醛酸酯衍生物之间的高度立体选择性α(1→4)偶联。设计该方法以制备在特定位置具有甲酯基的d-半乳糖醛酸低聚物。
