-galactopyranosyl)-4- O -methyl- chiro -inositol. In both syntheses, the imidate method of galactosylation was used on inositol derivatives having one axial and one equatorial hydroxyl-group free. Good selectivity of the reagent for the equatorial hydroxyl groups was demonstrated.
摘要合成了1 D -2- O-(α-D-半乳糖吡喃糖基)-4- O-甲基-手性肌醇,与先前从白三叶种子中分离出的半乳糖基松醇相同,并合成了一种异构体1 D- 5-O-(α-D-吡喃半乳糖基)-4-O-甲基-手性肌醇。在两个合成中,半乳糖基化的亚氨酸酯方法用于具有一个轴向和一个赤道羟基的肌醇衍生物。证明了该试剂对赤道羟基具有良好的选择性。
