We report a new approach for the synthesis of new chiral synthons in which two unsaturated sugars are linked via a glycosidic bond. The di-unsaturated disaccharide can be further functionalized using effective, highly selective methods and used in convergent syntheses of relatively complex glycoconjugates. Our approach utilizes in situ generation of active glycosyl donors via Ferrier-type rearrangement
我们报告了一种新的手性合成子合成的新方法,其中两个不饱和糖通过糖苷键连接。可以使用有效,高度选择性的方法将二不饱和二糖进一步官能化,并用于相对复杂的糖缀合物的融合合成中。我们的方法利用相转移条件下的Ferrier型重排原位生成活性糖基供体,并随后与亲核试剂反应。
