BF3.SiO2 nanoparticles: a solid phase acidic catalyst for efficient one-pot Hantzsch synthesis of 1, 4-dihydropyridines. (1st January 2013) - Sadeghi, Bahareh
The solvent-free Hantzsch reaction between ethyl acetoacetate or 1, 3-indandione, an aromatic aldehyde and ammonium acetate catalysed by BF3.SiO2 nanoparticles provided an efficient one-step synthesis of 1, 4-dihydropyridines in excellent yields.
