Synthesis, analysis and reduction of 2-nitropropyl starch

Heeres, André; Van Doren, Henk A.; Gotlieb, Kees F.; Bergsma, Jack; Kellogg, Richard M.; Bleeker, Ido Pieter

Granular 2-nitropropyl potato starch was synthesized by reaction with 2-nitropropyl acetate in an aqueous suspension. Nitroalkylation occurs preferentially with the amylose fraction of potato starch, as was confirmed by leaching experiments and digestion of the modified starch with α-amylase. The 2-nitropropyl …

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; 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 …
