The metal cations-polysaccharides complexes play crucial roles in the process of immune cell recognitions. Here, the authors create simpler biomimetic ligands, which emulate binding of carbohydrates in living organisms. The authors present a detailed study on the interactions of Cu2+, Ni2+ and VO2+ ions with t-Bu 3-azido- and 3-amino-2,3-dideoxy-α-D-arabino-hexopyranosides. NMR, IR and UV-visible spectroscopies as well as single crystal x-ray diffraction were used for the ligand structure determinations and showed their binding affinity of ions selected. The formation of stable complexes of Cu(II), Ni(II), VO(IV) ions and saccharides with 1:1, 1:2 and 1:3 molar ratios was proved. The coordination sites proposed are N-donor (amino or azido groups), O-donor (hydroxyl group) and endo-oxygen atoms. Addnl., parameters like shape, charge d. distribution, and sites of chem. reactivity of the sugars studied were obtained by mapping electron d. isosurface with electrostatic potential (MESP). The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).Related Products of 2873-29-2
