Magnetic chitosan hydrogel/PVA: a novel and efficient catalyst for the synthesis ofdihydropyrano [۲,۳-c] pyrazole and ۱,۴-dihydropyridine derivatives

The exploit of natural materials in the production of magnetic nanocomposites and the optimizationof syntheses can be considered as one of the main fields of research. In this regard, the catalytic applicationof PVA / cross-chitosan hydrogels in the synthesis of dihydropyrano [۲,۳-c] pyrazole and ۱,۴-dihydropyridinederivatives was investigated.
