The introduction of organoselenium moieties within the structure of carbohydrates has received attention recently. Herein, we report on the synthesis of selenium-containing neoglycoconjugates and pseudodisaccharides by the reaction of nucleophilic selenium species, generated from sugar diselenides, with chiral N-Boc aziridines and sugar tosylates. The reaction proceeds with moderate to good yields
在碳水化合物的结构中引入有机硒部分近来受到关注。在这里,我们报道了通过从糖二硒化物产生的亲核硒物种与手性N- Boc氮丙啶和糖甲苯磺酸盐的反应,合成了含硒的新糖结合物和假二糖。对于各种底物,反应以中等至良好的产率进行。在各种糖的框架内引入有机硒部分,具有增加的复杂度,从而允许合成二糖和糖缀合物模拟物。
