英文摘要：

2-Deoxy-glycosides are monosaccharides in which the hydroxyl group at C-2 is replaced with a hydrogen atom. They exist widely in natural products and show various bioactivity. The recent advances in organic synthesis of 2-deoxy-glycosides are summarized mainly focusing on direct etherification, direct glycosidic bond formation, temporary pro- tecting groups, synthesis from non-sugar and so on.
