sulfamidate group has been achieved by selective reduction of sulfamidate ketimine groups. The efficient access to the structurally unique glycals allowed the subsequent divergent synthesis of various naturally occurring 3-amino-2,3,6-trideoxysugars. In addition, Lewis acid-promoted glycosylation of the glycals provided a simple solution for the stereoselective installation of O- and C-linked aglycons on
具有顺式稠合环状磺酰胺基团的 3,5-顺式-3- 氨基甘醇的合成已通过选择性还原磺酰胺基酮亚胺基团实现。有效获取结构独特的糖醛允许随后不同地合成各种天然存在的 3-amino-2,3,6-trideoxysugars。此外,Lewis 酸促进的糖基化为氨基糖支架上 O 和 C 连接的糖苷配基的立体选择性安装提供了一种简单的解决方案。
