Реферат:
iAlkyl(hetero)aromatic -hydroxyamino oximes with the anti configuration of the oxime group reacted with ethyl glyoxylate to form 5-aryl(hetaryl)-1-hydroxy-1H-imidazole-2-carboxylic acid ethyl esters. In the case of 4-fluorophenyl-, 4-chlorophenyl-, and 4-methoxyphenyl-substituted -hydroxyamino oximes, 3-aryl-5-hydroxy-5,6-dihydro-4H-1,2,5-oxadiazine-6-carboxylic acid ethyl esters were also formed. The positions of the substituents in the imidazole ring were established on the basis of a comparative analysis of the spectroscopic data of these products and the synthesized isomeric compound, 1-hydroxy-5-methyl-4-phenyl-1H-imidazole-2-carboxylic acid ethyl ester. 5-Aryl(hetaryl)-1H-imidazole-2-carboxylic acids were obtained in the reaction of 5-aryl(hetaryl)-1-hydroxy-1H-imidazole-2-carboxylic acids ethyl esters with chloroacetone.
