Abstract 3-Carboxy-1-sulfopyridin-1-ium chloride ([CPySO3H]+Cl−) was synthesized and evaluated as a recoverable catalyst for one-pot synthesis of hexahydroquinoline-3-carboxamide derivatives by a four-component reaction of an arylaldehyde, dimedone, acetoacetanilide and ammonium acetate. The [CPySO3H]+Cl− catalyst was characterized by infrared (IR), 1H nuclear magnetic resonance (NMR), 13C NMR, elemental analysis and thermal gravimetric analysis (TGA).

A simple and benign protocol has been explored for the preparation of 2,4,6-triarylpyridines by a one-pot reaction between aryl aldehydes, enolizable ketones and ammonium acetate in the presence of N-bromosuccinimide or trichloroisocyanuric acid as green and neutral catalysts. The reactions proceed smoothly at 130 °C under solvent-free conditions to provide 2,4,6-triarylpyridines in good yields.
