Abstract :
The intramolecular cyclization of 2′-aminochalcones derived from 2- and 4-pyridinecarboxaldehydes was carried out in the presence of Amberlyst®-15/AcOH media. Unexpectedly, the reaction proceeded through a 5-exo process turning into an alternative approach for the synthesis of 2-(pyridinylmethylene)indolin-3-ones.
