Green Synthesis of 4H-pyran Derivatives Using Fe3O4-MNPs as Efficient Naliocatalyst: Study of Antioxidant Activity

摘要

Aims and Objective: In this work, pyran derivatives were synthesized via a multicomponent reaction of ninhydrin, alpha-haloketones, dialkyl acetylenedicarboxylate, and triphenylphosphine in the presence of iron oxide magnetic nanoparticles (Fe3O4-MNPs) as efficient nanocatalyst in ethanol at room temperature.
