The invention relates to a method for the preparation of glyco-conjugates of phosphorus amides with the general formula (See formula 1) where the connection of the sugar with the phosphorus amide-lost residue, and the ifosfamide-lost residue, resp., occurs preferably in the 1-position, and where R1 and R2, which can be the same or different, denote hydrogen, lower C1-C4 alkyl or C1-C6 haloalkyl and where as sugar there can be present mono-, di-, or polysaccharides in all existing isomeric and enantiomeric forms, wherein in a known way protected bromium sugars are conjugated with the respective phosphorus compounds, and freed of the protective residues, and to the use of said compounds as anti-tumour drugs.
