Gd0.7Sr0.3MnO3 perovskite as a novel and efficient catalyst for synthesis of dioxodecahydroacridine derivatives

In this work, perovskite-type material Gd0.7Sr0.3MnO3 was fabricated by sol-gel method. To prepare this nanopowder, metal salts, citric acid as the complexing agent, and water as solvent were used. A series of common analytical techniques were used to characterize the crystallinity, morphology, specific surface area, and grain size of the nanopowders. The composition and morphology of the nanopowders by energy-dispersive X-ray spectrometer and scanning electron microscopy is studied. BET analysis for surface accurate area of sample and Fourier transform infrared spectra were used to study the structure of nanopowders. Also, X-ray diffraction patterns show that the single perovskite phase is completely formed after calcination treatment. Moreover, in this study, 1,8-dioxodecahydroacridine derivatives were generated via one-pot four-component condensation, under solvent-free conditions at the presence of a perovskite as a new, efficient, heterogeneous, green, and recyclable catalyst with excellent yields.
