N-Propylsulfamic acid supported onto magnetic Fe۳O۴ nanoparticles (MNPs-PSA) as a green and reusable heterogeneous nanocatalyst Catalyst for the Synthesis of Highly Substituted Furans under solvent free conditions

A facile, rapid and solvent-free method for the conversion of for the preparation of highly functionalized tetra substituted furan derivatives by a one-pot condensation of but-۲-ene-۱,۴-diones and acetoacetate esters using N-Propylsulfamic acid supported onto magnetic Fe۳O۴ nanoparticles (MNPs-PSA) as a more robust and efficient catalyst under solvent free in good to excellent yields, is reported. The magnetic nanocatalyst can be readily recovered easily by applying an external magnet device and reused for at least ۱۰ reaction runs without considerable loss of reactivity.
