Efficient Continuous Flow Synthesis of Hydroxamic Acids and Suberoylanilide Hydroxamic Acid Preparation

The Journal of Organic Chemistry, 2009
A continuous flow tubing reactor can be used to readily transform methyl or ethyl carboxylic esters into the corresponding hydroxamic acids. Flow rate, reactor volume, and temperature were optimized for the preparation of a small collection of hydroxamic acids. Synthetic advantages were identified as an increased reaction rate and higher product purity.

Cyclic Hydroxamic Acids

1969
Publisher Summary This chapter summarizes the methods available for the synthesis of cyclic hydroxamic acids––to outline their characteristic reactions, and to present some useful physical data. Their synthesis, some biological and physical properties are also reviewed.

Hydroxamic acids I: Factors affecting the stability of the hydroxamic acid-iron complex

Journal of Pharmaceutical Sciences, 1969
The utility of hydroxamic acid formation and subsequent iron complexation as an analytical tool for succinimide has been investigated. Several factors affecting the stability of the hydroxamic acid-ferric iron complex have been studied and critical factors in the stability of the complex have been established.

Photochemistry of hydroxamic acids

Tetrahedron, 1987
Abstract Photochemical reactions of hydroxamic acids have been studied. The intermediacy of a RCONH radical is postulated, based on oxidations achieved with DCA under photochemical conditions.

Urease inhibition by hydroxamic acids

Experientia, 1981
Ureases from jack beans andRhodototorula pilimanae were observed to be inhibited by primary hydroxamic acids but were not inhibited by acyclic-secondary (N-alkyl) hydroxamic acids.

Hydroxamic acids. III. Mass spectra of substituted hydroxamic acids and cyclic imides

Australian Journal of Chemistry, 1969
Aryl hydroxamic acid derivatives fragment in a diagnostic manner upon electron impact. A hydroxamic acid containing both styryl and benzyl substituents undergoes skeletal-rearrangement of the type ABC ? AC+B. The mass spectra of the O- and N-acetyl derivatives of O- benzylhydroxamic acids are indistinguishable. M-CO2 fragments are again observed in the

Derivatives of hydroxamic acids

Applied Organometallic Chemistry, 2000
Despite the biological importance and rich chemistry of hydroxamic acids (HAs), their organometallic derivatives have received little attention so far. Fully silylated (trimethylsilyl and t-butyldimethylsilyl) derivatives which are promising for medicinal applications have a structure derived from that of the tautomeric hydroximic acid with an E/Z ...
