Abstract Under the conditions of in situ anomerisation, the 2-azido-4,6-di- O -benzoyl-2-deoxy-3- O -(2,3,4,6-tetra- O -acetyl-β- d -galactopyranosyl)-α- d -galactopyranosyl bromide reacted directly and with high selectivity with the reactive hydroxyl groups of l -serine and l -threonine derivatives to form α-glycosidically-linked products. Thus, the glycopeptides containing l -serine and l -threonine
摘要在原位异构化条件下,2-叠氮基-4,6-二-O-苯甲酰基-2-脱氧-3-O-(2,3,4,6-四-O-乙酰基-β-d -(半乳糖吡喃糖基)-α-d-半乳糖吡喃糖基溴与1-丝氨酸和1-苏氨酸衍生物的反应性羟基高选择性地直接反应,形成α-糖苷连接的产物。因此,更容易获得包含1-丝氨酸和1-苏氨酸的糖肽。二糖嵌段也可以与其他反应性羟基化合物偶联,以得到包含T受体的化合物。
