Abstract

The ultrasound-promoted glycosidation of several alcohols using 3,4,6-tri-O-acetyl-d-glucal as the glycosyl donor is described. The products were obtained in a short reaction time at room temperature in good yield and α-selectivity in an open flask, thus avoiding the preparation and manipulation of unstable or sensitive catalysts.
