Methyl tetra-O-allyl, and tetra-O-[2-(tetrahydro-2H-pyranyl) oxy.-3-oxapentyl glucosides, and tetra-O-(cyanoethyl) galactosyl azide were converted into derivatives containing linkers with terminal carboxylic acid functionalities at the anomeric position and bearing four arms with phthaloyl-or BOC-protected terminal amino groups. These molecules were suitable for use in solid-phase peptide synthesis and for the preparation of dendrimers containing multiple ...
