✦ Synopsis

The use of catalytic methylrhenium trioxide (MTO) and urea hydrogen peroxide in room temperature ionic liquid for the hydroxyglycosylation with glycals in a domino fashion is reported. Excellent conversions and good selectivities for the epoxidation reaction were observed. Application to the synthesis of glycosylphosphates, good glycosyl donors, has been studied.

## Abstract The efficient and high yielding domino epoxidation‐methanolysis of glycals **8**–**15** has been achieved by oxidation with UHP in MeOH catalyzed by MTO. The products have been conveniently isolated as 2‐acetoxy derivatives **16**–**23a,β€…b** by direct acetylation of the crude mixtures.
