Abstract
Abstract:
The development of an active, selective, and long-term selective catalyst for the synthesis of biologically active heterocycles is still challenging. However, magnetic nanocata-lysts have divergent applications like high efficiency, selectivity, consumption, and reusabil-ity. The current review explores a detailed survey of the latest information on synthetic meth-ods of Pyrano [3, 2-c] chromene derivatives using different magnetic nanocatalysts. Numer-ous studies on the synthesis of these practical compounds have been stimulated by the special qualities and wide-ranging applications of pyrano coumarins and the nanoparticles were tested for their catalytic effectiveness in a one-pot, three-component reaction involving aldehydes, malononitrile, and 4-hydroxycoumarin for the synthesis of dihydropyrano [3, 2-c] chromenes (coumarins).
