Abstract
γ-Alumina was found as a new efficient heterogeneous catalyst for the synthesis of pyran’s annulated heterocyclic systems. Three-component reaction of various aromatic aldehydes, malononitrile and cyclic CH-acids in the presence of γ-alumina in H2O as a green solvent at 50 °C gave pyran derivatives in high yields. γ-Alumina has some advantages such as cheap, available and recyclable.
