Synthesis of Heterocyclic Compounds Bearing Nitrogen and Oxygen Atoms Using Nano-kaoline/BF3/Fe3O4 Based on Green Chemistry in Different Conditions

چکیده مقاله

the widespread application of solid acids, structural and practical diversity of heterocyclic compounds containing N- or O- have prompted us to employ the novel and eco-friendly methods for the synthesis of heterocyclic compounds including: 3,4-dihydropyrimidin-2(1H)-ones, 1,4-dihydropyridines, 2,3-dihydro-1H-perimidines, N-arylpyrroles, and tetrahydro-4H-chromenes using nano-kaoline/BF3/Fe3O4 as a green catalyst under different conditions.
