Abstract: Condensation of 2-aroyl-6-hydroxy-3-methyl-5-acetyl-benzo­[b]­furan with different amines and paraformaldehyde in the presence of p-toluene sulfonic acid (PTSA) or PTC [tetra butyl ammonium sulphate] leads to the synthesis of benzo[b]furan Mannich bases by a solventless PTSA/PTC catalytic reaction under microwave irradiation.
