A simple and efficient procedure for the one pot Biginelli Condensation Reaction of aldehydes, β-ketoester and urea employing SnCl 4.5H2O/mono/di/tri-butyltin chloride as a novel catalyst is described. Compared to classical Biginelli
Vanadatesulfuric acid: A novel, recyclable, and heterogeneous catalyst for the one-pot synthesis of dihydropyrimidinones and dihydropyrimidinthiones under solvent-free conditions
Nasr-Esfahani, Masoud,Abdizadeh, Tooba
, p. 596 - 608 (2013/07/25)
Vanadatesulfuric acid (VSA), as a novel and heterogeneous catalyst, was used for an efficient synthesis of 3,4-dihydropyrimidin-2(1H)-ones (thiones) using an aldehyde, urea, or thiourea and an acyclic β-dicarbonyl compound under solvent-free conditions. V
A fast one-pot multi-component synthesis of 3,4-dihydropyrimidin-2(1h)-ones in the presence of magnesium oxide as a highly effective heterogeneous base catalyst
Mohammadzadeh, Iman,Bavafa, Mohammad,Sheibani, Hassan
, p. 773 - 777 (2014/06/24)
Magnesium oxide (MgO) effectively catalyzes the three-component reaction of aldehydes, urea and ethylacetoacetate to form 3,4-dihydropyrimidin-2(1H)-one derivatives. The effect of different kinds of magnesium oxide (MgO) such as commercially available, hi
