Abstract
In this research three simple methods including thermal, ultrasonic irradiation, and high speed milling method (HSBM) technique for preparation of pyrano[4,3-d]thiazolo[3,2-a]pyrimidine and chromeno[4,3-d]thiazolo[3,2-a]pyrimidines 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.
