A novel approach was developed for the synthesis of the pharmaceutically important morphine and dihydromorphine 6-β-d-glucuronides. The key step involves a selective 6-O-glycosylation of 3-O-protected morphines and dihydromorphines with thioglycosides that serve as glycosyl donors in the presence of thiophilic promoters. This novel approach may be useful for the O-glycosylation of other alkaloid derivatives.
针对合成在医药领域重要的吗啡和二氢吗啡-6-β-d-葡萄糖醛酸苷,开发了一种新颖的方法。关键步骤包括在硫亲和助推剂存在下,利用硫代糖苷作为糖基供体,对3-O-保护的吗啡和二氢吗啡进行选择性的6-O-糖基化反应。这一新颖方法可能对其他生物碱衍生物的O-糖基化具有应用价值。
