Synthesis, reactions and antimicrobial studies of α-aryl-N-(2-nitrocyclohexyl)nitrones
摘要:
Synthesis of the title compounds from several aryl aldehydes and 2-nitrocyclohexylhydroxylamine has been described and the action of base on these compounds has been investigated. They have all been tested for their antimicrobial activity against the microorganisms such as Staphylococcus aureus, Escherichia coli, Klebsiella aerogenes, Proteus mirabilis, Salmonella paratyphi, Salmonella typhi and Pseudomonas sp and the results are discussed.

A reaction of aliphatic 1,2-hydroxylamino oximes bearing the hydroxylamino group at the secondary carbon atom with aromatic and heteroaromatic aldehydes in acetic acid leads to the corresponding 1-hydroxy-2-aryl(hetaryl)-4,5-dialkylimidazoles in high yields. α-Aryl(hetaryl)-nitrones initially formed by the condensation of 1,2-hydroxylamino oximes with aldehydes are quantitatively converted to the corresponding imidazoles.
