A cubic phase of pure MgO nanopowders was prepared in an aqueous solution containing freshly squeezed orange juice with pulp and characterized by X‐ray diffraction (XRD), field emission scanning electron microscopy (FE‐SEM), energy‐dispersive X‐ray spectroscopy (EDS), and Fourier transform infrared (FT‐IR) spectroscopic techniques. The catalytic potential of MgO nanopowders was evaluated in preparation of pyrano[4,3‐d]thiazolo[3,2‐a]pyrimidine and chromeno[4,3‐d]thiazolo[3,2‐a]pyrimidines derivatives using the three simple methods including thermal, ultrasonic irradiation, and high‐speed ball milling (HSBM) technique under solvent‐free conditions. All products were successfully formed in high yields.
