selective removal of the primary benzyl group or selective acetolysis of the primary benzyl group of β-C-glycoside as key steps. Such structures have been successfully used as scaffolds for the synthesis of novel saccharide nucleosides. (© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
已经通过 TMSOTf/Ac2O 介导的 α-C-糖基化制备了几种带有 α- 或 β-C
D-吡喃葡萄糖基主链的糖
叠氮基或
氨基酯,同时选择性去除初级苄基或选择性乙酰化初级苄基β-C-糖苷作为关键步骤。此类结构已成功用作合成新型糖核苷的支架。(© Wiley-
