sources (IDCP and NIS/TfOH) as activators. IDCP- or NIS/TfOH-assisted glycosidation of sugar 1,2 thio ortho esters with primary hydroxyl groups of “armed” or “disarmed” ethyl (phenyl) 1-thioglycosides gave the respective disaccharides having 1,2 ortho ester or 1,2 trans interglycosidic linkages.
可以使用
碘鎓离子源(IDCP和NIS / TfOH)作为活化剂,将糖1,2
硫代原酸酯与末端糖基受体缩合。IDCP或NIS / TfOH辅助的具有“武装”或“解除武装”的乙基(苯基)1-
硫代糖苷的伯羟基的糖1,2
硫代原酸酯的糖基化作用,分别得到具有1,2
邻苯二甲酸酯或1,2的二糖反糖苷间键。
