The reaction mechanism postulated by Wolfrom, Schuetz and Cavalieri87 for the formation of 5-(hydroxymethyl)-2-furaldehyde from D-glucose involves the enol (XXXV) of 3-deoxy-D-glucosone as an intermediate an alternative pathway proposed by these same workers included the enol...

Another important aspect of the Maillard reaction involves the Strecker degradation of ot-amino acids. At elevated temperatures oe-dicarbonyl compounds, such as 3-deoxy glucosone, pyruvaldehyde, glyoxal, and dihydroascorbic acid will cause the degradation of an... 

Because the phenylosazone and tetrahydroxybutylquinoxaline derivatives of D-glucosone have been isolated from 1-deoxy-l-p-toluidino-D-fruc-tose in high yields, 1,2-enolization of the aminodeoxyketose must predominate over 2,3-enolization. No proof for 2,3-enolization is known at present. The sequence of reactions (in alkali) which lead from the aminodeoxyketose (XVI) through the 1,2-enediol (XVIII) to the glycosone (XIX) are thought to be as follows ... 

The nomenclature of 3-deoxyglycosuloses (3-deoxyglycosones) will follow the revised Rules of Carbohydrate Nomenclature thus, (1) is 3-deoxy-n-eryUnsaturated sugars will be... 

Comparison of major mass spectrum peaks from diphenylhydrazone 0-acetylated derivatives of glucose (a), glucosone (b) and 4-deoxy-4-fluoro-glucosone (c)... 

Selective and H-labelling, and NMR spectroscopy, have been used to show that the 3-deoxy-D-e77t/iro-hexos-2-ulose (3-deoxy-D-glucosone) degrades to 3-deoxy-D-nfeo-hexonic acid and 3-deoxy-D-ara mo-hexonic acid via an intramolecular 1,2-hydrogen transfer mechanism in aqueous phosphate buffer. 

Ribofuranosyl derivatives of substituted benzimidazoles have been found to have virus inhibitory activity (44)-From glucosone, compounds with quinoxaline structures may be produced (4S), In the presence of hydrazine and o-phenylenediamine, 1-deoxy-1-p-toluino-D-fructose or -D-tagatose is converted to a quinoxaline compound in the pH range 6 to 8 by a mechanism similar to osazone formation 46),...
