Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The recyclization in an acidic medium of enamino ketones that are imidazolidine derivatives leads to 1-pyrrolin-4-one 1-oxide derivatives, viz., cyclic Β-oxo nitrones, which exist in the form of equilibrium mixtures of the ene hydroxyamino keto and oxo nitrone tautomeric forms, the ratio of which depends on the solvent and the character of the substituent.
