2-deoxy substituent Z is azido, amino, propionamido, or acetamido, were prepared by chemical synthesis. Both types of modified trisaccharides are acceptors for a fucosyltransferase preparation obtained from human milk. Preparative fucosylations using this enzyme provided analogues of the sialylLewis(x) and sialylLewis(a) tetrasaccharide structures, which have been proposed to be ligands for cell-adhesion
