The reported method is mild, rapid and has the advantages such as heterogeneous catalysis, simple work-up procedure, recyclability of the catalyst and purification of products without chromatographic methods.}, number={2}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Shirini, Farhad and Atghia, Seyyed Vahid and Khoshdel, Meysam Alipour}, year={2024}, month={Feb.}, keywords={Nanocrystalline TiO2, Polyhydorquinolie derivatives, one-pot condensation reaction., Heterogeneous catalysis, Hantzsch reaction.} }
