The use of allyl protecting group mediated intramolecular aglycon delivery (IAD) as a strategy for intramolecular glycosylation has been extended to allow the stereoselective synthesis of α-glucofuranosides and β-rhamnopyranosides, in a totally stereoselective fashion. The efficiency of intramolecular glycosylation is dependent on the protecting group pattern of the glycosyl donor, and on the steric
使用烯丙基保护基介导的分子内糖苷配基(IAD)作为分子内糖基化的策略已得到扩展,以完全立体选择性的方式允许α-葡糖呋喃糖苷和β-鼠李糖吡喃糖苷的立体选择性合成。分子内糖基化的效率取决于糖基供体的保护基团模式以及糖基受体的空间体积。
