(homoallylglycine, Hag) as a “tag” for modification and a photoinitiated hydroglycothiolation reaction that is selective only for the Hag olefinic “tag”. Application of this method to a number of model proteins allowed complete and precise site‐selective glycosylation generating glycoconjugates that include, for example, virus‐like particles displaying up to 180 glycans at preselected positions (see scheme).
标记为硫醇化:一种新的糖缀合策略利用非天然含烯烃的氨基酸(高烯丙基甘氨酸,Hag)作为修饰的“标签”和仅对 Hag 烯烃“标签”有选择性的光引发氢糖硫醇化反应。将此方法应用于许多模型蛋白,可以实现完整和精确的位点选择性糖基化生成糖缀合物,例如,在预选位置显示多达 180 个聚糖的病毒样颗粒(参见方案)。
Stereoretentive Palladium-Catalyzed Arylation, Alkenylation, and Alkynylation of 1-Thiosugars and Thiols Using Aminobiphenyl Palladacycle Precatalyst at Room Temperature
A general and efficient protocol for the palladium‐catalyzed functionalization of mono‐ and polyglycosyl thiols by using the palladacycleprecatalyst G3‐XantPhos was developed. The CS bond‐forming reaction was achieved rapidly at roomtemperature with various functionalized (hetero)aryl‐, alkenyl‐, and alkynyl halides. The functional group tolerance on the electrophilic partner is typically high and
We demonstrated −OH as the deacylation catalyst in methanol, indicating that the Zemplén condition had been misleading us for almost 90 years.
我们在甲醇中展示了-OH作为脱酰催化剂,表明Zemplén条件在近90年里一直误导着我们。

serial inversion was successfully applied in the efficient synthesis of 2-thio- or 2,4-di-thio-mannoside derivatives. The protein recognition properties of the synthesized positionalthiolanalogs of mannose were then evaluated in a competition binding assay with the model lectin Concanavalin A (Con A), in order to investigate the roles of thiol group in the different position of the mannopyranose ring
