TL;DR: In this paper, a 2-step, 1-pot procedure for the stereoselective glycosylation of allylic alcohols with 1,2-di-O -benzoyl-β- d -glucopyranosides was developed.
Abstract: A new 2-step, 1-pot procedure for the stereoselective glycosylation of allylic alcohols with 1,2-di- O -benzoyl-β- d -glucopyranosides to produce 2-hydroxy-β- d glucopyranosides has been developed. The required precursor for the glycosylation was readily obtained from tri- O -benzyl- d -glucal in 2 steps (91% overall).
TL;DR: In this article, the ultrasound-promoted glycosidation of several alcohols using 3,4,6-tri-O-acetyl-d -glucal as the glycosyl donor is described.
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.
