A simple, economical, three‐component, and one‐pot synthesis of novels spiro[indoline‐3,5′‐pyrido[2,3‐ d ]pyrimidine] derivatives by condensation of dimethyl acetylene dicarboxylate, isatin derivatives, and 6‐amino‐1,3‐dimethyluracil in presence of Fe 3 O 4 @Propylsilane@Histidine[HSO 4 − ] as an impressive catalyst via reflux and ultrasound procedure is described. The results show that ultrasound method has several advantages such as milder condition, shorter reaction time, and higher reaction yield.
