Chemoselective formation of glycoconjugates from unprotected glycans is needed to further develop chemical biology involving glycans. Carbohydrate oxime formation is often slow, and organocatalysis by anilines would be highly promising. Here, we present that carbohydrate oxime formation can be catalyzed with up to 20-fold increases in overall reaction rate at 100 mM aniline. Application of this methodology provided
从未保护的聚糖的糖缀合物的化学选择性形成是进一步发展涉及聚糖的化学生物学所需要的。碳水化合物肟的形成通常很慢,而苯胺的有机催化将很有前途。在这里,我们提出在100 mM苯胺中,碳水化合物肟的形成可被催化,其总反应速率最多可增加20倍。该方法的应用提供了对复杂糖缀合物的访问。
