Abstract
Silica-supported Preyssler nanoparticles (SPNP) was found to be an inexpensive and effective catalyst for the rapid, one-pot three-component synthesis of N-substituted 1,8-dioxodecahydroacridines in high yields, with easy workup procedure. The nanocatalyst was easily separated from the reaction mixture and was recycled a couple of times without any appreciable loss in activity. In addition, water as a green solvent was a solvent of choice.
