چکیده
|
Fe3o4@cys–so3h magnetic nanocatalyst has been used as an effective and reusable solid acid catalyst for the one pot synthesis of novel spiro[chromeno[4′,3′:3,4]pyrazolo[1,2-b]phthalazine-7,3′-indoline]-2′,6,9,14-tetraone via a three-component reaction of phthalhydrazide, 4-hydroxycoumarin and isatin derivatives. easy separation of catalyst, good yields of reaction and synthesis of novel heterocyclic compound are some advantages of this procedure.
