[BMIm]HSO4 as a Green and Highly Efficient Catalyst for One-pot Synthesis of 3-Substituted Indoles under Ultrasound Irradiation
A practical and green synthesis of 3-substituted indoles is reported via three-component coupling reaction of indoles, aldehydes and N-methylaniline in the presence of the acidic ionic liquid 1-butyl-3-methylimidazolium hydrogen sulfate ([BMIm]HSO4) under ultrasound irradiation at room temperature. The significant features of this procedure are high yields of the products, simple work-up, opera...
متن کاملMontmorillonite modified as an efficient and environment friendly catalyst for one- pot synthesis of 3, 4-dihydropyrimidine-2(1H) ones
Montmorillonite modified is an efficient environmental friendly catalyst under one-pot-three-component synthesis of 3,4-dihydropyrimidine-2(1H) ones. The preparation was performed with an aldehyde, 1,3-dicarbonyl compounds, urea or thiourea under solvent-free conditions. In comparison with the other methods of Biginelli reaction, this new method has short reaction time inexpensive catalyst and ...
