C-2 Epimerization of aldoses and ketoses catalyzed by the Ni(II) complex is described. Both epimerization and the preparation of side-chained sugars proceed in the ternary nickel complex through stereospecific rearrangement of the carbon skeleton, that is, from (1-13 C)-D-glucose into (2-13 C)-D-mannose and from (2-13 C)-D-fructose into (2-13 C)-D-hamamelose, and vice versa. The structure of the ligand in the complex plays an important role during the epimerization. The epimerization proceeds more smoothly in both methanolic and aqueous solutions with a more hydrophobic ligand such as N,N¢-higher alkylated ethylenediamine. Due to their ability to self-aggregate in water, the organized metallomicelles can provide an appropriate reaction system for the epimerization of aldoses. The chirality of the ligand contributes to the shift of the equilibrium between the two C-2 epimers.

“…We are investigating the coordination polymers derived from aldaric acids with transition metals, lanthanides, and other metals; herein we report chiral zinc D ‐saccharate, which is exceptional in that its structure contains two types of parallel channels with very different characteristics, one type hydrophilic the other hydrophobic, which are isolated from each other by seemingly impenetrable walls. In 1998 it was shown that copper( II ) saccharate has a linear polymeric chain structure,2 and the structures of the potassium and calcium salts were described earlier 3. The structures of a number of Group 1 and 2 metal derivatives of galactaric acid (also known as mucic acid) were reported (Na,4 K,4 Mg,5 Ca6 and Ba6).…”

Zinc Saccharate: A Robust, 3D Coordination Network with Two Types of Isolated, Parallel Channels, One Hydrophilic and the Other Hydrophobic

Ein schachbrettartiges Muster: Saccharinsäure, eine billige chirale Ausgangsverbindung für mögliche „grüne“ heterogene Katalysatoren und Molekularsiebe, bildet ein stabiles kristallines Zinkderivat, dessen Kristallstruktur zwei Typen von Kanälen, einen hydrophilen und einen hydrophoben, mit stark unterschiedlichen Merkmalen enthält. Die Kanäle sind durch anscheinend undurchdringliche Wände getrennt, wodurch ein schachbrettartiges Muster entsteht (siehe Bild).

“…[1] With possibilities such as these in mind, we have undertaken an investigation of the metal derivatives of saccharic acid and have previously reported the synthesis, structure and sorption properties of a microporous zinc derivative. [2] d-Saccharate derivatives of Zn, [2] Co, [2] Mn, [3] Cu, [4] K 2 , [5] K/Na, [6] KH, [6] K/Al [7] and Ca [8] have been structurally characterised by X-ray crystallography, and the ligand has been shown to bind from two to six metal centres. Very recently a series of linear coordination polymers of the saccharate ion with the co-ligands 2,2'-bipyridine and 1,10-phenanthroline (hereafter phen) was described.…”

The combination of Cu(NO(3))(2), potassium hydrogen saccharate (KC(6)H(9)O(8)) and 1,10-phenanthroline (phen) yields a pair of chiral cluster compounds, each with composition Cu(21)(C(6)H(5)O(8))(6)(phen)(12)(NO(3))(12) ⋅solvate. One of the compounds forms as orthorhombic crystals, while the other forms cubic crystals. Each of the clusters has D(3) or approximate D(3) symmetry, but the arrangement of the saccharate ion in the clusters is quite different in the two cases. The clusters in the cubic form interact with neighbouring clusters through face-to-face π interactions involving the phen ligands, an association that leads to the generation of very large solvent-filled spaces in the crystal structure. In contrast the clusters in the orthorhombic form are much more densely packed. At the centre of each cluster that crystallises in the orthorhombic form is a nitrate anion that binds to six Cu(II) centres. ESI mass spectral studies indicate that the Cu(21) clusters exist in solution. Solid-state magnetic studies of the cubic form of Cu(21) show that antiferromagnetic coupling occurs to leave a non-zero-spin ground state, and comparisons are made to the magnetic data for other large Cu(II) clusters.
