    • Abstract

       

      Silica-bonded 𝑆-sulfonic acid is employed as a recyclable catalyst for the synthesis of naphthoxazinone derivatives from the reaction of 𝛽-naphthol, aromatic aldehydes and urea at 150°C under solvent-free conditions. The heterogeneous catalyst was recycled for five runs after the reaction of 𝛽-naphthol, benzaldehyde and urea without losing its catalytic activity.
