Summary: Beta-methyl-D-glucofururonohydroxamic acid sodium salt, the first sugar-hydroxamic acid was synthesized starting from gama-lactone of beta-methyl-D-glucofufuronoside and characterized by its physical properties and 13C NMR and IR spectral data.Coordination ability of beta-methyl-D-glucofururonohydroxamic acid toward the iron(III)in aqueous solution was studied.

Title: Reaction of the carbonyl group with nitroso compounds. The cases of pyruvic acid and acetaldehyde

Authors:: Uršić, Stanko; Pilepić, Viktor; Vrček, Valerije; Gabričević, Mario; Zorc, Branka

Journal: Journal of the Chemical Society, Perkin Transactions 2
Number: 2

Volume: 93
Year: 1993
Pages: from 509 to 514
Number of references: 42
Language: engleski
Summary: Pyruvic acid and acetaldehyde react with substituted nitrosobenzenes to give the corresponding N-phenylacetohydroxamic acids. A mechanism for these reactions involving three sequential steps is proposed.
Keywords: Pyruvic acid, Acetaldehyde, Hydroxamic acids, Nitrosobenzenes, Cyclic transition state, Decarboxylation

Title: Reactions of carbonyl group with nitroso compounds. Reaction of formaldehyde with substituted nitrosobenzenes

Authors:: Uršić, Stanko

Journal: Helvetica Chimica Acta
ISSN: 0018-019
Volume: 76
Year: 1993
Pages: from 131 to 138
Number of references: 33
Language: engleski
Summary: Formaldehyde reacts with substituted nitrozobenzenes giving the corresponding N-phenylhydroxamic acids. A mechanism involving three sequential steps in this reaction is proposed. The first step is the nucleophilic attack of the nitroso group on the carbonyl group which leads to the formation of the unstable zwitterionic intermediate followed by the proton transfer to form more stable nitrosocarbinolic cation intermediate, which in the subsequent step undergoes the rate-controlling elimination of proton from the C-atom of nitrosocarbinolic group, leading to the hydroxamic acid.
Keywords: Formaldehyde, Nitrosobenzene, Nitroso nucleophyle, zwitterionic intermediate, Proton transfer

Title: 13C and 1H NMR Line Broadening in Desferrioxamine B Spectra. Kinetics and Mechanism of Siderophore Chemistry

Authors:: Biruš, Mladen; Gabričević, Mario; Klaić, Branimir; Kronja, Olga

Journal: Inorganic Chemistry
ISSN: 0020-1669
Volume: 34
Year: 1995
Pages: from 3110 to 3113
Number of references: 25
Language: engleski
Summary: A slow rotation around C-N bonds of naturally occuring trishydroxamato acid, desferrioxamine B, was investigated by 1H, 13C dynamic NMR tecniques. Corresponding rate constants for the C-terminal, middle and N-terminal hydroxamates are 12, 15, 9, respectively. The E-form of hydroxamate dominates over Z-form in an approximate ratio 4:1. The slow rotation around the C-N bond of the middle hydroxamato group is proposed to be the rate determining step in dechelation of the middle hydroxamato group in ferrioxamine B. The rate of the E/Z isomerization og the C-terminal hydroxamate group is found to be the rate determining step in the complexation of La(III) and Cu(II) with desferrioxamine B.

Title: Reaction of 2-Niroso-2-Methyl Propane with Formaldehyde, Glyoxylate and Glyoxylic Acid.

Authors:: Pilepić, Viktor; Uršić, Stanko

Journal: Tetrahedron Letters
Number: 40
ISSN: 0040-4039
Volume: 35
Year: 1994
Pages: from 7425 to 7428
Number of references: 17
Language: engleski
Summary: 2-nitroso-2-methyl propane reacts with formaldehyde, glyoxylate, glyoxylic, pyruvic and phenylglyoxylic acid giving the corresponding N-t-buthyl hydroxamic acids. These reactions involve formation of the dipolar addition intermediates and 2-nitroso-2-methyl propane acts as a nucleophile in the reaction step in which these intermediates are formed.
Keywords: 2-nitroso-2-methyl propane, nitroso nucleophile, formaldehyde, glyoxylic acid, pyruvic acid, phenylglyoxylic acid, hydroxamic acids, reaction mechanism.
