چکیده مقاله :
Tetrahydrobenzo[b]pyrans are heterocyclic compounds, which are important because of their wide application in medicinal and biological features [1]. Many of these properties are known for their anticancer, anti-inflammatory, antimicrobial, anti-HIV, antibacterial, and antiproliferative activities. Recently, different homogeneous and heterogeneous catalysts have been applied for preparation of Tetrahydrobenzo[b]pyrans, such as KOH-loaded CaO [2] and NH2@SiO2@Fe3O4 MNPs [3] catalysts. 1,4-Diazobicyclo [2.2.2] octane (DABCO) is a commercially accessible, affordable, and most widespread catalyst that is used in organic reactions. Further, DABCO was taken into account as one of the foremost catalysts for the multi-component synthesis of dihydropyrano[c]chromene derivatives [4]. Thus, the main purpose of the present work is the synthesis of nano-Fe3O4@dextrin/Si(CH2)3/DABCO (NFDSiPD) as a new and natural-based magnetic nanocatalyst for one-pot preparation of tetrahydrobenzo[b]pyran derivatives via condensation of various aldehydes, malononitrile, and dimedone
