Barium silicate nanoparticles, an efficient catalyst for one-pot green synthesis of α-benzyl amino coumarin derivatives as potential chemotherapeutic agents.

A new, simple, and efficient method for synthesis of α-benzyl amino coumarin and its derivatives (1-24) is described a one-pot, three-component condensation of aromatic aldehydes, amine, and 4-hydroxycoumarin under green chemistry conditions: water as a solvent and BaSiO nanoparticles as catalyst. BaSiO nanoparticles and all synthesized derivatives were characterized by multiple methods including; XRD, NMR, and FE-SEM. This method which gives higher yields, is also less expensive, and more environmentally friendly compared with other methods in the literature. physicochemical and pharmacokinetics analyses were done on all synthesized compounds and indicated that these α-benzyl amino coumarins would be effective scaffolds for the future development of chemotherapeutic agents.
