摘　　要：以D-木糖及D-葡萄糖为原料,经具有降冰片结构的双环缩醛中间体,合成了适当羟基保护的五元环氮杂糖衍生物及其氟代衍生物,进一步探讨了含氮杂糖结构的双糖衍生物的合成.The derivatives of polyhydroxylated pyrrolidines have exhibited a remarkable biological activity to inhibit glycoside-processing enzymes, and found a potential chemotherapeutic applications against diabetes, cancer, and viral infections including AIDS. And great attention has been attracted to the synthesis of their new derivatives and analogues. In this paper, some new derivatives of 5-membered azasugars with partially protected hydroxy groups, and their fluorinated ones were synthesized via the key intermediate of norbonyl like bicyclic acetal with D-xylose and D-glucose as the starting materials. The glycosylation of the synthesized partially protected azasugar and 1-methylenesugar was explored.
