Memarian, Hamid Reza,Ranjbar, Mahnaz
experimental part, p. 522 - 527 (2012/01/05)
Efficient synthesis of various 2-oxo(thioxo)-1,2,3,4-tetrahydropyrimidines containing acetyl, carboethoxy, carbomethoxy and carboxamide groups on 5-position of the M-substituted and ATL-unsubstituted heterocyclic ring was achieved using cobalt hydrogen su
A convenient one-pot Biginelli reaction catalyzed by Y(OAc)3: An improved protocol for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones and their sulfur analogues
Aridoss, Gopalakrishnan,Jeong, Yeon Tae
experimental part, p. 863 - 868 (2010/10/19)
Yttrium(III) acetate hydrate-catalyzed novel synthesis of 3,4-dihydropyrimidin-2(1H)-(thio)one derivatives was achieved through one-pot three-component condensation of diversified aldehydes, β-ketoesters and urea or N-methylurea or thiourea with a molar r
Expedient Synthesis of Biginelli-Type Dihydropyrimidinones Using α-(Benzotriazolyl)alkyl Urea Derivatives
Abdel-Fattah, Ashraf A. A.
, p. 2358 - 2362 (2007/10/03)
Reaction of readily available α-(benzotriazolyl)alkyl urea derivatives (derived from aromatic, heteroaromatic, and aliphatic aldehydes) with β-keto esters resulted in 3,4-dihydropyrimidin-2(1H)-ones in good to excellent yields.
