CeO2/CuO@N-GQDs@NH2 nanocomposite as a reusable and efficient catalyst for the synthesis of piperidines

An efficient pseudo six-component synthesis of bis-spiropiperidinesis presented by one-pot condensation of formaldehyde, aromatic amine and dimedone or N,N-dimethyl-barbituric acid using CeO2/CuO@N-GQDs@NH2 nanocomposite at room temperature. The catalyst has been characterized by SEM, FT-IR, XRD, ED...
