Synthesis of amino-bridged oligosaccharides using reductive amination opens rapid access to novel glycomimetic target structures as potential ligands for the receptor protein NKR P1 of natural killer cells. Emphasis was laid on fast and facile synthetic routes. The carbonyl building blocks were easily obtained by oxidation with Dess-Martin periodinane or iodoxybenzoic acid (IBX). For the required

by a facile synthesis of such motifs. Employing chemoenzymatic methods, several modified Galβ1-3GalNAc derivatives were synthesized. Modifications were introduced at the stage of the monomeric building blocks prior to formation of the disaccharides by means of four different β-galactosidases from bovine testes, Bacilluscirculans and Xanthomonas manihotis as well as the phosphorylase from Bifidobacterium
