摘要

FeCl3/C作为一种高效便捷的启动子，通过对3,4,6-三- o -苄基- d -葡聚糖的铁离子型重排进行糖基化，而葡聚糖是该类型反应的相对不活跃的底物。该方法适用于多种醇类，尤其是酚类。在温和的条件下，该方法高效地制备了一系列2,3-不饱和o -糖苷(47-92%)。

FeCl3/C as an efficient catalyst for Ferrier rearrangement of 3,4,6-tri-O-Benzyl-D-glucal

FeCl₃/C was used as an efficient and convenient promoter for glycosylation through Ferrier-type rearrangement of 3,4,6-tri-O-benzyl-D-glucal, which is a relatively unreactive substrate for this type of reaction. The method was applicable to a wide range of alcohols, especially phenols. A series of 2,3-unsaturated-O-glucosides were prepared efficiently (47–92%) by this method under mild conditions.
