[图解]我们报道了一种新的海藻糖类似物的合成,它涉及到使用分子内苷元传递来立体选择性地形成1,1-α,α-糖苷键。糖基化反应以较高的产率得到了所需的异构体。
[GRAPHICS]We report a new synthesis of trehalose analogs that involves the use of intramolecular aglycone delivery for stereoselective formation of the 1,1-alpha,alpha-glycosidic bond. The glycosylation reaction afforded the desired isomer exclusively and in good yield.
