TL;DR: The 3-deoxyglycosuloses as intermediates in the formation of metasaccharinic acids by the action of alkali on reducing sugars appears to be influenced by cationic catalysis, more of the arabino epimer being formed with sodium hydroxide.
Abstract: Publisher Summary This chapter discusses the 3-deoxyglycosuloses as intermediates in the formation of metasaccharinic acids by the action of alkali on reducing sugars The part played by 3-deoxyglycosuloses and their enolic forms, and by unsaturated glycosuloses, in the degradation of carbohydrates dealt, particularly with respect to the formation of 2-furaldehydes 3-Deoxyglycosuloses are included in the review on dicarbonyl carbohydrates 3-Deoxy-D-erythro-hexosulose is obtained as a colorless, hygroscopic powder of empirical formula C 6 H 10 O 5 The compound is soluble in water, methanol, and ethanol, but insoluble in dry acetone, ethyl acetate, and ether Osazones are readily formed from 3-deoxy-Derythro-hexosulose in the presence or absence of acid The reactions proceed more rapidly with calcium hydroxide than with sodium hydroxide, and the stereospecificity of the benzilic acid rearrangement appears to be influenced by cationic catalysis, more of the arabino epimer being formed with sodium hydroxide

TL;DR: The arabinosazones facilitated superior analyses in providing a highly uniform distribution of sample molecules within the matrix microcrystals, and a possibility of using low laser energy for irradiation, leading to high spectral resolution and low matrix background.

TL;DR: In this paper, the structural and configurational assignments were based on the mode of preparation and from spectroscopic data, most conveniently from p.m. spectra and chiroptical properties.

TL;DR: Homologous structures postulated for phenyldiimideferrihemoglobin and nitrosobenzeneferrohemoglobin suggest a common factor in the production of Heinz bodies after exposure of erythrocytes to phenylhydrazine and to arylamines.
Abstract: Phenylhydrazine is oxidized stoichiometrically by two equivalents of ferricyanide to produce phenyldiimide and ferrocyanide. This reaction permits accurate determination of the absorption maxima and molar absorption coefficients of phenyldiimide in aqueous solution. These values are identical or extremely similar to those of phenyldiimide produced by decarboxylation of phenylazoformic acid. Knowledge of the stoichiometry of the reaction confirms an earlier suggestion that phenyldiimide is the product of ferricyanide-oxidized phenylhydrazine that reacts with heme proteins. Homologous structures postulated for phenyldiimideferrihemoglobin and nitrosobenzeneferrohemoglobin suggest a common factor in the production of Heinz bodies after exposure of erythrocytes to phenylhydrazine and to arylamines.
