Dioximes of 1,3-diketones enter into the Trofimov reaction forming pyrroles containing an acyl or an O-vinyloxime substituent in position 3 of the pyrrole. In the case of sterically hindered dioximes the main reaction products are isoxazoles. 2005 Springer Science+Business Media, Inc.

According to the data from 1H and 13C NMR spectroscopy, the dioximes of β-carbonyl compounds exist in solutions in the dioxime form, represented by a series of configurational isomers, or as a mixture of the dioxime and the cyclic isoxazoline forms.The conditions for the appearance of the ring-chain equilibrium in the dioximes of β-dicarbonyl compounds were determined, and the dependence of the tautomeric and configurational composition on the structure of the β-dicarbonyl component and the nature of the solvent was studied.
