alcohols using a palladium-catalyzed glycosylation reaction. The 1,4- and 1,6-alpha-manno-disaccharides were achieved in seven total steps starting from chiral furan alcohols. Similarly, 1,4- and 1,6-alpha-manno-trisaccharides were also synthesized in nine total steps. Key to the overall efficiency of this process was the use of highly diastereoselective palladium-catalyzed glycosylations, reductions,
使用钯催化的糖基化反应从呋喃醇合成天然的全 d-和/或非天然的全 1,4-和 1,6-寡糖。1,4- 和 1,6-α-甘露糖-二糖是从手性呋喃醇开始的七个总步骤中获得的。类似地,1,4-和1,6-α-甘露糖三糖也分九个总步骤合成。该过程整体效率的关键是使用高度非对映选择性钯催化的糖基化、还原和二羟基化。
