Abstract
AbstractA green and simple method for the synthesis of the title compounds 4 by the reaction of 5-chloroacetyl-8-hydroxyquinoline (1), pentane-2,4-dione (2), and amines 3 in the presence of a catalytic amount of 1,4-diazabicyclo[2.2.2]octane at 60°C is described. The procedure is amenable for the synthesis of other substituted pyrroles. Short reaction time, environmentally friendly procedure, and excellent yields are the main advantages. The structures of products 4a–n were characterized by 1H NMR, IR, and MS spectra.
