Abstract
In this research, three simple methods including thermal, ultrasonic irradiation, and high-speed milling method (HSBM) techniques for the preparation of pyrano[4,3-d]thiazolo[3,2-a]pyrimidine derivatives in the presence of MgO nanopowders under solvent-free conditions has been reported. MgO nanopowders were prepared in an aqueous solution containing freshly squeezed orange juice with pulp and characterized by XRD, FE-SEM, EDS, and FT-IR techniques.
