A chitosan‐based magnetic nanocomposite was synthesized by an eco‐friendly and simple procedure, and was characterized using scanning electron microscopy , energy‐dispersive X‐ray spectroscopy, X‐ray diffraction and Fourier transform infrared spectroscopy . It was then used for the efficient synthesis of tetrahydrobenzoxanthen‐11‐one derivatives via a one‐pot three‐component condensation of 2‐naphthol, various aldehydes and dimedone in ethanol. The catalyst was recovered easily and reused several times without significant loss of catalytic activity . Copyright © 2016 John Wiley & Sons, Ltd.
