In this research the magnetite nanoparticles supported silica sulfonic acid(Fe3O4@SiO2@OSO3H) was used as a green and efficient catalyst for the preparation ofoctahydroquinazolinone derivatives as biologically active heterocyclic compounds. Thisprocedure avoids hazardous reagents, solvents, catalyst and can be an eco-friendly alternativeto the existing methods. The one-p...
