Preparation of 2-unsubstituted 5-aryl(hetaryl)-1-hydroxy-1H-imidazoles from of 4-aryl(hetaryl)-1-hydroxy-2,5-dihydro-1H-imidazole-2-carboxylic acid 3-oxides
Alkylaromatic 1-hydroxyamino-2-oximes reacted at the hydroxyamino group with glyoxylic acid hydrate, providing 4-aryl(hetaryl)-1-hydroxy-2,5-dihydro-1H-imidazole-2-carboxylic acid 3-oxides that were converted upon heating into 5-aryl(hetaryl)-1-hydroxy-1H-imidazoles containing a hydrogen atom at the heterocycle position 2.
期刊介绍：
The international journal Chemistry of Heterocyclic Compounds publishes original papers, short communications, reviews, and mini-reviews dealing with problems in the field of heterocyclic chemistry in Russian and English. The Journal also publishes reviews and annotations on new books and brief reports on conferences in the field of heterocyclic chemistry, as well as commemoratives dedicated to prominent heterocyclic chemists.
