摘要
Silica sulfuric acid as a heterogeneous reagent catalysed eco-friendly and efficient synthesis of 2,3-dihydroquinazolinones by the reaction of isatoic anhydride, a primary amine or ammonium acetate and an aromatic aldehyde in water or under solvent-free conditions. The solid acidic catalyst could be recycled and reused. (c) 2007 Published by Elsevier B.V..
