The stereoselective syntheses of one pentasaccharide and one tetrasaccharide containing the Glc-alpha-(1-->3)-Man-alpha moiety as their terminal unit, as well as one tetrasaccharide and one trisaccharide containing the Man-alpha-(1-->2)-Man-alpha terminal unit were accomplished through the utilization of two key glycosyl donors, namely, 4-pentenyl 3-O-acetyl-2,4,6-tri-O-benzyl-alpha-D-mannopyranoside
包含Glc-alpha-(1-> 3)-Man-alpha部分作为末端单元的一种五糖和一种四糖以及包含Man-alpha-(1--的一种四糖和一种三糖的立体选择性合成> 2)-Man-alpha末端单元是通过利用两个关键的糖基供体来完成的,即4-戊烯基3-O-乙酰基-2,4,6-三-O-苄基-alpha-D-甘露吡喃糖苷和乙基2-O-乙酰基-3,4,6-三-O-苄基-1-硫代-α-D-甘露吡喃糖苷。
