This invention relates to compounds of general formula I, in which S is a carbohydrate core matrix; a is a pharmaceutically active moiety; L is a linker a covalent bond; n is an integer of 2 to 19; and R' is hydrogen, thioalkyl or X-Z in which Z is a lipophilic anchor and X is a linker or covalent bond. Formulae Va, Vb and Vc where R4-R9 are as defined in the specification; and delivery systems for pharmaceutically active agents.

-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
