A new method of synthesis of indolyl glycoses

Autor: Yu. A. Zhdanov, V. I. Kornilov, G. V. Bogdanova

Publikováno v: Carbohydrate Research. 4:492-497

The copper-catalysed decomposition of acetylated 1-deoxy-1-diazoketoses in the presence of indole affords acetates of higher 1-deoxy-1-(indol-3-yl)ketoses. The constitution of the products was indicated by elemental analysis, infrared and ultraviolet

Condensation of al-forms of sugars with pyridine salts containing an active N-methylene group

Autor: Yu. A. Zhdanov, N. N. Artamonova, G. V. Bogdanova

Publikováno v: Chemistry of Heterocyclic Compounds. 2:426-428

A crotonaldehyde type of condensation takes place in acetic anhydride between phenacylpyridinium iodide and al-D-glucose or al-D-galactose, to give mono-products, while al-D-mannose heptaacetate gives a di-product. If the heating time is increased, a

Synthesis and some chemical transformations of nitro- and nitraza-dicarboxylic acids

Autor: I. S. Ivanov, Yu. V. Konnova, T. A. Alekseeva, G. V. Bogdanova, S. S. Novikov

Publikováno v: Bulletin of the Academy of Sciences, USSR Division of Chemical Science. 15:719-721

1. Theγ-nitro- andγ-nitro-γ-methylpimelic acids and some of their derivatives were synthesized. 2. The dissociation constants of the nitro acids were determined by potentiometric titration. The introduction of either one or two nitro groups in the

Condensation of al-sugars with barbituric acid

Autor: Yu. A. Zhdanov, G. V. Bogdanova

Publikováno v: Chemistry of Heterocyclic Compounds. 2:41-43

Al-D-glucose and al-D-galactose pentaacetates and al-D-mannose heptaacetate are condensed with barbituric acid in 10% acetic acid to give a bis-product I, while in ethanol, water, and 50% ethanol, a mono-product I is formed.

Condensation of al-forms of sugars with thiobarbituric and iminobarbituric acids

Autor: Yu. A. Zhdanov, G. V. Bogdanova

Publikováno v: Chemistry of Heterocyclic Compounds. 2:597-599

Fully acetylated al-D-glucose, al-D-galactose, and al-d-mannose condense with thiobarbituric acid in ethanol to give di-products, with deacetylation of the sugar portion, which latter, in the cases of the diproducts from glucose and galactose, is a (
