Glycoclusters were obtained by N-alkylation of N-glycyl-β-d-galactopyranosylamine with N-chloroacetyl derivatives of β-d-galactopyranosylamine and N,N″-iminodiacetyl-di-β-d-galactopyranosylamine. The glycoclusters with two and three galactopyranosylamine residues and the monovalent ligand N-diglycyl-β-d-galactopyranosylamine with an amino group in the spacer are suitable for subsequent conjugation with carboxyl-containing physiologically active compounds.
