Abstract

[Figure not available: see fulltext.] A novel superparamagnetic iron oxide modified with copper via 2-aminobenzamide is synthesized by the modification of Fe3O4@SiO2 with amine, followed by the reaction with isatoic anhydride. The catalyst is fully characterized by various methods. The catalytic activity of the catalyst is evaluated in the synthesis of a series of novel N-alkyl-2-aryl-2-(6-oxo-6,7-dihydro[1,2,3]triazolo[1,5-a]pyrazin-5(4H)-yl)acetamide analogs. Antibacterial activity of the synthesized compounds is evaluated. The catalyst is recoverable and shows excellent reusability in 10 sequential runs. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.
