A new method for the synthesis of 2-indolyl-1-nitroalkanes from indoles and β-nitrostyrene via Michael addition catalyzed by [ Cu (3,4-tmtppa)] (MeSO4)4 as a reusable catalyst under solvent-free conditions is described. This method has been also successfully applied for Michael addition of 3-methyl-1-phenyl-5-pyrazolone with β-nitrostyrenes.

High Yields

H2SO4-Silica efficiently catalyzes the three-component condensation reaction of aldehydes, 1,3-dicarbonyl compounds and urea/thiourea under solvent free conditions to afford the corresponding dihydropyrimidinones and thio-derivatives in high yields. Compared to the classical Biginelli reaction conditions, this new method consistently has the advantage of giving good yields and requiring short reaction times.
