Resumen:
Several dihydropyrimidinones/thiones, 1,4- dihydropyridines, and pyridine derivatives were prepared in very good yields and purity values. The corresponding reactions were carried out by employing a bulk Preyssler heteropolyacid H14[NaP5W29MoO110] as an efficient and recyclable catalyst. The preparation of pyridine derivatives was carried out not through a usual procedure, i.e., the opening of the γ- pyrone ring of 3- formylchromone. In general, reactions took place in solvent- free conditions at 80°C during short reaction times.Simple and ecofriendly synthesis of dihydropyrimidinones (thiones), dihydropyridines, and pyridines using 3- formylchromones as substrates assisted by a recyclable Preyssler heteropolyacid
