[ 1 ] - Oxalic acid dihydrate catalyzed synthesis of 3,4-dihydropyrimidin-2-(1H)-one derivatives under thermal and solvent-free conditions
Oxalic acid dihydrate as a green, mild and efficient catalyst for the one-pot three-component Biginelli synthesis of 3,4-dihydropyrimidin-2-(1H)-one derivatives from the reaction between β-keto esters (methyl or ethyl acetoacetate), aromatic aldehyde (benzaldehye derivatives) and urea or thiourea under thermal and solvent-free conditions with excellent yields and short reaction time is st...
[ 2 ] - Fe2O3 as an Environmentally Benign Natural Catalyst for One-Pot and Solvent-Free Synthesis of Spiro-4H-Pyran Derivatives
In this work, a simple and economical procedure for the synthesis of spiro-4H-pyranderivatives has been found through the three-component, one-pot condensation of isatin/acenaphthequinone, malononitrile and different reagents including 1, 3-dicrbonyl compounds, naphthol and 4-hydroxycumarin under thermal and solvent-free conditions in the presence ofFe2O<su...
[ 3 ] - An Efficient Synthesis of 3,4-Dihydropyrimidin-2-(1H)-one Derivatives Promoted by Antimony Trichloride under Thermal and Solvent-free Conditions
An efficient and simple one-pot approach for the synthesis of 3,4-dihydropyrimidin-2-(1H)-one derivatives using antimony trichloride (SbCl3) as a mild catalyst by means of three-component Biginelli reaction between β-keto esters, aldehyde derivatives and urea/thiourea under thermal and solvent-free conditions with excellent yields and short reaction times is reported. This m...
