✦ Synopsis

Abstract

The reaction of α‐hydroxyamino ketones 1 with diacetyl, acetyl acetone or acetoacetic ester in the presence of ammonium acetate results in the formation of 3‐imidazoline derivatives 2, which are precursors for the synthesis of stable nitroxides 8, 9, 14, 16, 17, 23–24 with various functional groups in the side chain at the 2‐position of the heterocycle.
