metal–organic framework-based catalyst CoFe 2 O 4 @SiO 2 @IRMOF-3 was prepared and identified as an efficient catalyst for the synthesis of a variety of functionalized dihydro-2-oxopyrroles by a one-pot, four-component reaction of a dialkyl acetylenedicarboxylate, an aryl amine, formaldehyde, and optionally a second amine or diamine at room temperature. The catalyst was magnetically separated and recovered
