preparation of sucrose-based macrocycles via a click chemistry route. This was realized by protection of the 6′‒OH with silyl block followed by elongation of the glucose end with the ‒CH2CH2N3 unit. Removal of the silyl block and subsequent propargylation of the released C6′‒OH afforded the corresponding synthon, cyclization of which under the click condition provided the desired macrocycle with the expected
摘要 1',2,3,3',4,4'-Hexa-O-benzyl-sucrose 通过点击化学途径制备蔗糖基大环化合物。这是通过用甲硅烷基嵌段保护 6'-OH 然后用 ‒CH2CH2N3 单元延伸葡萄糖末端来实现的。去除甲硅烷基嵌段和随后释放的 C6'-OH 的炔丙基化提供相应的合成子,在点击条件下环化其提供所需的大环,在三唑环上具有预期的 1,4-模式取代基。
