Ag-SiO2 Nanoparticles: Benign, Expedient, and Facile Nano Catalyst in Synthesis of Decahydroacridines

A simple approach for component reaction between aldehydes, anilines or ammonium acetate, and dimedone in ethanol as a solvent is studied using Ag-SiO2 nanoparticles. This approach results for the synthesis of various decahydroacridines in appropriate yields (80-94%). The use of Ag-SiO2 nanoparticles as a heterogeneous catalyst lets a clean procedure.
