Phosphorylation of benzoylated ethyl 1,2-trans 1-thioglycosides with dibenzyl phosphate in the presence of NIS gave, after removal of all protecting groups, 1,2-trans glycosyl phosphates. The scope of the stereoselective method was demonstrated by the synthesis of GDP-fucose and the disaccharide α-d-Glcp-(1→3)-α-l-Rhap-1-PO4−.
在除去所有保护基团后,在NIS存在下用磷酸二苄基酯对苯甲酰化的1,2-反式1-硫代1-硫代糖苷进行磷酸化,得到1,2-反式糖基磷酸酯。立体选择性方法的范围是由GDP-岩藻糖的合成,所述二糖α-d-GLC证实p(1→3)-α-L-鼠李糖- p -1-PO 4 - 。
