Abstract
A new core–shell magnetic silica functionalized with 3,4-diaminobenzoic acid nanocatalyst (Fe<sub>3</sub>O<sub>4</sub>@SiO<sub>2</sub>@PTS-DABA) was prepared and characterized. The Fe<sub>3</sub>O<sub>4</sub>@SiO<sub>2</sub>@PTS-DABA catalyst was applied for the synthesis of dihydropyranopyrazole and benzylpyrazolyl coumarin derivatives.
