Recently, there has been a growing interest in the synthesis of multivalent carbohydrate assemblies due to their ability to target multiple receptors simultaneously. In the present work, a protective group strategy, based on the methodology originally developed by Crich, has been utilized for the homodimerization of olefinic carbohydrates, allowing a highly diastereoselective synthesis of some divalent structures
数项研究已将(1→2)-连接的甘露聚糖作为生物学上相关的化合物。最近,由于多价碳水化合物组装体同时靶向多种受体的能力,人们对合成它们的兴趣日益增长。在本工作中,基于Crich最初开发的方法的保护基策略已用于烯烃碳水化合物的均二聚化,从而允许高度非对映选择性地合成某些二价结构。此外,显示了二价供体可以进行偶联反应而没有立体选择性或效率的损失。所述策略可潜在地应用于多种新糖缀合物和寡糖的合成。 碳水化合物-二价分子-非对映选择性合成-均二聚-(1→2)-连接的甘露聚糖
