✦ Synopsis

The trisaccharide a-D-Manp-( l-+2)-a-D-Manp-(l-+2)-D-Man was synthesised by using a stepwise method. A key reaction in the preparation of the intermediates was the selective hydrogenolysis of mannopyranoside derivatives having both dioxane-and dioxolane-type benzylidene acetals, resulting in the exclusive cleavage of the former acetal rings.
