A variety of new glycosylglycerol derivatives have been prepared by stereoselective dihydroxylation of a range of alkenyl β-D-hexopyanosides under Donohoe's conditions. We have studied the relationship between the diastereoisomeric excess and the structural features of the precursor (sugar and alkenyl moieties). The stereochemical yields demonstrated that the presence of a hydrogen-bond donor group
在 Donohoe 条件下,通过一系列烯基 β-D-己酮苷的立体选择性二羟基化,制备了多种新的糖基甘油衍生物。我们研究了非对映异构体过量与前体(糖和烯基部分)的结构特征之间的关系。立体化学产率表明糖部分的 2 位存在氢键供体基团 (OH, NHAc) 是获得高水平立体识别力所必需的。新的 1-O-酰基-3-O-β-D-糖基-sn-甘油类似物是通过用脂肪酸对伯羟基进行官能化而获得的。还提供了糖基甘油和糖基甘油脂类似物的初步细胞毒活性分析。
