title: Efficient intramolecular beta-mannoside formation using m-xylylene and isophthaloyl derivatives as rigid spacers.
abstract: A series of mannosyl donors linked via position 2 to an m-xylylene or an isophthaloyl spacer which was connected to the position 6 of a glucoside acceptor afforded, via intramolecular glycosylation, the corresponding disaccharides with high beta anomeric ratio.
