Organosilane sulfonated graphene oxide in the Biginelli and Biginelli-like reactions
Safari, Javad,Gandomi-Ravandi, Soheila,Ashiri, Samira
, p. 512 - 520 (2016)
Organosilane sulfonated graphene oxides (SSi-GO) have been synthesized by a two-step procedure involving the grafting of graphene oxide (GO) using 3-chloropropyltriethoxysilane (CCPTES) and subsequent oxidation using sulfanilic acid. It has been shown tha
Green Biginelli-type Reaction: Solvent-free Synthesis of 5-unsubstituted 3,4-dihydropyrimdin-2(1H)-ones

, p. 1907 - 1910 (2015/11/09)
The Biginelli-type compounds, 5-unsubstituted 3,4-dihydropyrimdin-2(1H)-ones were synthesized by a one-pot three-component condensation of aromatic aldehydes, aromatic ketones and urea in the presence of SnCl4 · 5H2O under solvent-fr
Synthesis of 3,4-dihydropyrimidin-2(1H)ones and 3,4,5,6,7,8- hexahydroquinazolin-2(1H)-ones via three component cyclocondensation

experimental part, p. 346 - 350 (2010/10/03)
3,4 Dihydropyrimidin-2(1H)-ones and 3,4,5,6,7,8-hexahydroquinazolin-2(1H)- ones have been synthesized from the condensation of ketones, aldehydes and urea/thiourea in the presence of sodium tertiary butoxide by the solventless microwave irradiation (MWI)
Iodotrimethylsilane-accelerated one-pot synthesis of 5-unsubstituted 3,4-dihydropyrimidin-2(1H)-ones: A novel procedure for the Biginelli-like cyclocondensation reaction at room temperature

, p. 2996 - 2999 (2007/10/03)
A novel Biginelli-like cyclocondensation reaction is efficiently catalyzed by iodotrimethylsilane (Me3SiI) in MeCN. The reaction proceeds at room temperature by a three-component one-pot condensation of ketones with aldehydes and urea to afford
Reaction of α,β-Unsaturated Ketones with Urea. Synthesis and Spectral Properties of 2(1H)-Pyrimidinone Derivatives

, p. 512 - 514 (2007/10/02)
1,3-Diaryl-2-propen-1-ones react with urea to give 4,6-diaryl-3,4-dihydropyrimidinones (IVa-g) that can be further oxidized to the corresponding dehydro analogues (Va-f).The latter compounds are also obtained via interaction of aroylphenylacetylenes with urea.Spectral data, supporting the suggested structures IV and V, are presented.
