In the present work, Cu@KCC‐1‐NH‐CS 2 as a green, efficient, and reusable nano‐reactor was designed and used for the one‐pot, three‐component synthesis of 2‐amino‐4 H ‐chromene derivatives using the reaction of cyclic 1,3‐diketones, arylglyoxals, and malononitrile, under reflux conditions in EtOH. Engineered nanocatalyst characterized using different methods including scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT‐IR), adsorption/desorption analysis (BET), and energy dispersive X‐ray spectroscopy (EDS). According to the obtained results, presented protocol for the synthesis of 2‐amino‐4 H ‐chromenes using Cu@KCC‐1‐NH‐CS 2 gave the desired products in higher yields (89–98%) with short reaction times. Also, under mild reaction conditions this green nanocatalyst indicated recyclable behavior five times with minor reduce in its catalytic activity.
