The catalyst was characterized by XRD, SEM, TG, BET and FT-IR techniques. This method has advantages of high yield, moderate to excellent diasteroselectivity, mild condition, catalyst recyclability, and simple work-up procedure.}, number={1}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Massah, Ahmad Reza and Kalbasi, Roozbeh Javad and Toghyani, Mitra}, year={2024}, month={Feb.}, keywords={OMMT/PS-SO3H, Nano composite, Solvent-free, Mannich reaction, β-amino carbonyl compound} }
