In the interaction of 5-hydroxypyrazolidines with acetophenone on the surface of basic adsorbents, regioisomeric 3-benzoylmethylpyrazolidine was formed along with expected 5-benzoylmethylpyrazolidine as a consequence of the retro-Michael degradation of the starting compounds followed by an attack of crotonaldehyde at the imide nitrogen atom.
