Abstract

An effective method to prepare the substrate of alpha-L-fucosidase (AFU) is described. Ethyl 1-thiofucoside with a free 2-OH group was used as the glycosyl donor, and there was found no self-condensed side product. The use of the HF.pyridine reagent to remove the silyl protecting group in the last step afforded a target molecule of high purity.
