Safari, Javad,Gandomi-Ravandi, Soheila
, p. 147 - 154 (2015)
A supported carbon material is shown to be a highly efficient, eco-friendly and recyclable solid acid catalyst for the Biginelli reaction of aldehyde, β-ketoester and urea or thiourea under microwave irradiation in the absence of solvent. This method offe
Synthesis of 3,4-dihydropyrimidin-2(1H)-one via one-pot Biginelli reaction under solvent-free conditions
Peng, Huan,Hu, Yulin,Xing, Rong,Fang, Dong
, p. 2053 - 2058 (2015)
Three novel heteropolyanion-based acidic ionic liquids, [TMAPS]H2PMo12O40, [TEAPS]H2PMo12O40, and [TBAPS]H2PMo12O40, were used as efficient catalysts for th
Studies on the Biginelli reaction: A mild and selective route to 3,4-dihydropyrimidin-2(1H)-ones via enamine intermediates
Mabry, John,Ganem, Bruce
, p. 55 - 56 (2006)
L-Proline methyl ester hydrochloride was found to be an effective catalyst for assembling (±)-dihydropyrimidinones under mild conditions. Mechanistic insights into the useful selectivity elements of this amine-catalyzed process are also reported.
One-pot synthesis of 3,4-dihydropyrimidin-2(1H)-ones using chloroacetic acid as catalyst
