SbCl3 as an Efficient Catalyst for the One-pot Synthesis of Highly Substituted Piperidines

Highly substituted piperidines were synthesized via the condensation of aromatic aldehydes and aromatic amines with β-ketoesters in the presence of antimony(III) chloride at ambient condition. This reaction has any advantages such as easy work-up, clean procedure, and good yields.

[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...

Pr3+ doped CoFe2O4: A highly efficient, magnetically recoverable and reusable catalyst for one-pot four-component synthesis of multisubstituted pyrroles

A facile and highly efficient one-pot synthesis of multisubstituted pyrrole derivatives is reported via a four-component reaction of amines, aldehydes, acetylacetone and nitromethane using Pr3+ doped CoFe2O4 as a catalyst in solvent free conditions at 90°C. The catalyst is easily recoverable using magnet and could be reused without a significant loss of catalyti...
