Synthesis and reduction of 2-nitroalkyl polysaccharide ethers

Heeres, A. (Biobased Ingredients And Materials); Spoelma, F. F.; Van Doren, H. A.; Gotlieb, K. F.; Kellogg, R. M.; Bleeker, Ido Pieter

Several 2-nitroalkyl polysaccharide ethers (from pullulan (1), guar (2), agarose (3), inulin (4), cellulose (5), Na-α-polyglucuronate (6) and hydroxyethyl cellulose (7)) were synthesized by reaction with 2-nitro-1-alkenes (2-nitro-1-propene and 2-nitro-1-butene) formed in situ from 2-nitroalkyl acetates. …

Cross-linking of starch with bifunctional precursors of nitroalkenes

Heeres, André (Biobased Ingredients And Materials); Van Doren, Henk A.; Gotlieb, Kees F.; Kellogg, R. M.; Bleeker, Ido Pieter

Granular starch was cross-linked with 1,3-di-O-acetyl-2-nitro-1,3-propanediol (1), 1,3-di-O-pivaloyl-2-nitro-1,3-propanediol (2), 2-nitro-3-O-pivaloyl-1-propene-3-ol (3), 1,3-di-O-acetyl-aci-2-nitro-1,3-propanediol (4), 1,3-di-O-pivaloyl-aci-2-nitro-1,3-propanediol (5) and 1,6-di-O-acetyl-2,5-dinitro-1,6-hexanediol …

Synthesis of α- and β-D-glucopyranuronate 1-phosphate and α-D-glucopyranuronate 1-fluoride: intermediates in the synthesis of D-glucuronic acid from starch

Heeres, André (Biobased Ingredients And Materials); Van Doren, Henk A.; Gotlieb, Kees F.; Bleeker, Ido Pieter

The title uronates were prepared by 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) catalysed sodium hypochlorite oxidation of α- and β-D-glucopyranosylphosphate (α-/β-Glc-1-P) and α-D-glucopyranosyl fluoride (α-Glc-1-F). Quantitative recovery of the TEMPO catalyst was achieved by azeotropic distillation …
