Abstract

• Excellent yields (95–97%) in short reaction times (<10 min). • Superb reusable (8 times) catalyst 2.5 %CeO 2 /TiO 2 . • Synthesis of methyleneisoxazole-5(4H)-one analogues. • One-pot/three-component green solvent (aqueous ethanol) protocol. • Easy recovery catalyst and cost effective reagents. A novel and efficient nanocomposite is synthesized by deposition–precipitation approach, characterized by FE-SEM, SEM-EDX, P-XRD, TEM, TGA and BET analyses. P-XRD and N2 sorption investigations of 2.5 mol% CeO 2 /TiO 2 confirmed the amorphous mesoporous nature of CeO 2 /TiO 2 , which possessed a specific surface area of 110.6 m 2 .g ─1 and an average pore size 83 nm. Then, SEM and TEM ascertained the disordered pores in their morphology. Further, the catalytic activity of the prepared nanocomposite was applied for the synthesis of methyleneisoxazole-5(4H)-one analogue via one-pot and multicomponent reaction of substituted aldehyde, ethyl acetoacetate and hydroxylamine in the presence of ultrasound irradiation under eco-friendly manner. Simple handling, utilization of readily accessible starting materials, elimination of toxic solvents, environmental-friendly, easy workup, cleaner reaction profile, high product yields (94–99%) and short reaction times (≤10 mints), recyclability, and reusability are several benefits of this approach.
