title: Environmentally benign and stereoselective formation of beta-mannosidic linkages utilizing 2,3-di-O-benzyl-4,6-O-benzylidene-protected mannopyranosyl phosphite and montmorillonite K-10.
abstract: An environmentally benign and stereoselective beta-mannopyranosylation has been developed employing 4,6-O-benzylidene-protected mannopyranosyl diethyl phosphite as a glycosyl donor and montmorillonite K-10 as an activator.
