Coumarin derivatives were synthesized using magnetically recoverable iron oxide nanoparticles supported
amino acids as heterogeneous catalysts via one-pot multi component reaction using MW irradiation. Easy recovery of the
catalyst using an external magnet, efficient recycling, and reusable without significant loss of their catalytic efficiency
makes the protocol greener and sustainable.
