摘要
An acidic nanocatalyst SBA-15-SO3H with a high surface area and high acid content was readily synthesized, characterized, and effectively used in the synthesis of some new and known pyrido[2,3-d:6,5-d']dipyrimidine derivatives by condensation reaction of 6-aminouracil and different aldehydes under solvent-free conditions. The catalyst was reused for 6 runs without significant loss of its activity. Short reaction times, high yield of the products, solvent-free conditions, and use of a robust and reusable catalyst are worthwhile advantages of the present method.
