Highly efficient one-pot four-component synthesis of polyhydroquinoline derivatives catalyzed by stannous chloride under solvent-free conditions
A rapid and efficient one-pot, four-component protocol towards the synthesis of polyhydroquinoline derivatives has been developed. The condensation of aldehyde, dimedone, ethyl acetoacetate and ammonium acetate in presence of stannous chloride was carried out under solvent free condition to synthesize a variety of polyhydroquinoline derivatives in good to excellent yields. Stannous chloride was...

متن کاملChemoselective Synthesis of Pentaerythritol Diacetals Catalyzed by CuO-CeO2 Nanocomposite under Solvent-free Conditions
CuO-CeO2 nanocomposite is reported as a green recyclable catalyst for the chemoselective synthesis of pentaerythritol diacetals from aromatic aldehydes under solvent-free conditions. The catalyst was synthesized by co-precipitation method and characterized by XRD, BET specific surface area, FESEM and EDS analysis. This procedure provides some advantages such as simple work-up, clean procedure, ...
