Synthesis of Imidazo[1,2-a]pyridines Using Fe3O4@SiO2 as an Efficient Nanomagnetic Catalyst via a One-Pot Multicomponent Reaction

A one‐pot multicomponent synthesis of imidazo[1,2‐a]pyridine derivatives by using pyridin‐2‐amines, aldehydes, and terminal alkynes in the presence of a catalytic amount of silica‐supported iron oxide (Fe3O4@SiO2) nanoparticles in refluxing EtOH in good‐to‐excellent yields is reported.
