N-Propylsulfamic acid supported onto magnetic Fe۳O۴ nanoparticles (MNPs-PSA) as a green and reusable heterogeneous Nano catalyst for the synthesis of ۱'۸-dioxo-octahydroxanthene derivatives under solvent free conditions

An efficient and eco-friendly method is reported for the synthesis of ۱'۸-dioxo-octahydroxanthene in good to high yields using N-Propylsulfamic acid supported onto magnetic Fe۳O۴ nanoparticles (MNPs-PSA) under solvent-free conditions at room temperature. The magnetic Nano catalyst can be readily recovered easily by applying an external magnet device and reused for at least ۱۰ reaction runs without considerable loss of reactivity.
