These macrocyclic compounds are qualified to act as synthetic catalysts due to their specific features including being able to form host\u2010guest complexes, having unique structural scaffolds and their relative ease of chemical modifications with a variety of functions on their upper rim and lower rim. Here, a functional magnetic nanocatalyst was designed and synthesized by using a synthetic amino\u2010functionalized calix[4]arene. Its catalytic activity was evaluated in a one\u2010pot synthesis of 2\u2010amino\u2010<jats:italic>4H<\/jats:italic>\u2010chromene derivatives.
