The present invention provides a one-pot method of preparing an unprotected α-O-glycolipid. The first step involves contacting a protected α-iodo sugar with a catalyst and a lipid comprising a hydroxy group, under conditions sufficient to prepare a protected α-O-glycolipid. The second step involves deprotecting the protected α-O-glycolipid under conditions sufficient to prepare the unprotected α-O-glycolipid, wherein the contacting and deprotecting steps are performed in a single vessel. The present invention also provides a one-pot method of preparing an unprotected β-O-glycolipid following the steps for the preparation of the unprotected α-O-glycolipid.
本发明提供了一种制备未保护的α-O-糖脂的一锅法。第一步涉及将受保护的α-碘糖与催化剂和含有羟基的脂质接触,在足够的条件下制备受保护的α-O-糖脂。第二步涉及在足够的条件下去除受保护的α-O-糖脂的保护基,制备未保护的α-O-糖脂,其中接触和去保护步骤在单个容器中进行。本发明还提供了一种制备未保护的β-O-糖脂的一锅法,遵循制备未保护的α-O-糖脂的步骤。
