Also, the reaction of aromatic aldehyde and 4-hydroxycoumarin in the presence of L-proline (20 mol%) in the ethanol under reflux conditions, lead to biscoumarin derivatives}, number={2}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Zahiri, Samaneh and Mokhtary, Masoud and Torabi, Mogharab}, year={2024}, month={Feb.}, keywords={Mannich type reaction, Betti base, Multicomponent reaction, Biscoumarin, L-proline} }
