Environmentally benign and stereoselective formation of β-O-glycosidic linkages using benzyl-protected glucopyranosyl phosphite and montmorillonite K-10

An environmentally benign and highly stereoselective β-glucopyranosylation without neighboring group participation has been developed employing benzyl-protected glucopyranosyl diethyl phosphite as a glycosyl donor and montmorillonite K-10 as an activator.
