de novo synthetic strategy for the production of oligosaccharides containing 2,3,6‐trideoxypyranoglycoside is reported. The key event is the Pd‐catalyzed asymmetric diastereoselective hydroalkoxylation of ene‐alkoxyallene‐linked glycosidic fragments. The utility of this approach was demonstrated by the activation‐free, stereodivergent, and convergent synthesis of various 2‐deoxyoligosaccharides, as well
报道了从头合成策略生产含2,3,6-三苯氧基吡喃吡喃糖苷的寡糖。关键事件是Pd催化的烯-烷氧基丙二烯连接的糖苷片段的不对称非对映选择性加氢烷氧基化反应。各种2-脱氧寡糖及其糖苷配基的无活化,立体发散和会聚合成证明了这种方法的实用性。
