Glycodendrons are multivalent glycoconjugates bearing an orthogonal functional group at the focal point of the molecule. This allows for their postsynthetic elaboration to achieve amphiphilic glycolipid mimetics, for example, which eventually can be applied in biology, biophysics, or material science. Here, postsynthetic modification of di- and tetravalent polyether glycodendrons has been explored using etherification, thiol-ene reaction and in particular olefin cross metathesis.
糖树脂是多价糖共轭物,其分子焦点处带有正交功能基团。这使得它们能够进行后合成改造,以实现两性糖脂类似物,最终可以应用于生物学、生物物理学或材料科学。在这里,使用醚化反应、硫醇-烯烃反应和特别是烯烃交叉⽐特⽅法,探索了二价和四价聚醚糖树脂的后合成修饰。
