An efficient α-sialylation method for many primary hydroxyl acceptors that include 6-OH glycosides has been developed. 7,8-Di-O-picoloyl sialyl glycoside was used as the glycosyl donor, and α-glycoconjugation was controlled by using the 7,8-di-O-picoloyl moiety in CHCl. The methodology was successfully applied to the total synthesis of ganglioside Hp-s1 possessing neuritogenic activity.
已经开发出一种用于许多包括 6-OH 糖苷在内的伯羟基受体的高效α-唾液酸化方法。7,8-二-O-对甲酰基唾液酰基糖苷被用作糖基供体,并且通过在 CHCl 中使用 7,8-二-O-对甲酰基部分来控制α-糖缀合。该方法成功地应用于具有神经突生成活性的神经节苷脂 Hp-s1 的全合成。
