Abstract
This article describes the synthesis of iron oxide/hydroxyapatite (Fe3O4/HAp) nanocomposite by the hydrothermal method and utilization of Fe3O4/HAp as a competent, reusable, magnetically separable nano-composite catalyst for one-pot synthesis of 3,4-dihydropyrimidin-2(1H)-one derivatives by cyclo-condensation of dicarbonyl compound, aryl-aldehydes and (thio)urea in EtOH:H2O (1:1, v/v) as an eco-safe solvent. The Fe3O4/HAp nano-catalyst was characterized by spectral and analytical techniques such as FT-IR, SEM, XRD, EDX and VSM. The advantage of this procedure includes excellent product yield in a shorter time, a simple workup procedure, reusability of the catalyst, and avoidance of volatile organic solvent, and strong mineral acid.
