چکیده

-chromene derivative was obtained in 97% yield within 7 min. The catalyst showed high recyclability and only a slight decrease in its corresponding activity was observed after several cycles of use, which indicates its structural stability and recyclability. Amine-enriched biochar is a highly effective, eco-friendly, and reusable (5-cycle) nanocatalyst for the synthesis of critical pharmaceutical heterocycles. It is a greener substitute for conventional catalysts and it helps researchers to move forward with green synthesis approaches.
