products, drug candidates, glycopeptide mimics, oligosaccharide analogues, and other applications, but the efficiency of these reactions is usually limited by slow reaction times. Here, we show that aniline derivatives such as 2-amino-5-methoxybenzoic acid enhance the rate of acid-catalyzed neoglycosylation for a range of sugar substrates up to a factor of 32 relative to the uncatalyzed reaction.
新糖基化越来越多地用于天然产物,候选药物,糖肽模拟物,寡糖类似物和其他应用的合成中,但这些反应的效率通常受到反应时间缓慢的限制。在这里,我们显示了苯胺衍生物(例如2-氨基-5-甲氧基苯甲酸)可提高糖催化范围内酸催化新糖基化的速率,相对于未催化反应而言,该比率最高可达32倍。
